The resting place of Bahá’u’lláh’s earthly remains is at Bahjí, the holiest place on earth for Bahá’ís.

It is clear and evident that when the veils that conceal the realities of the manifestations of the Names and Attributes of God, nay of all created things visible or invisible, have been rent asunder, nothing except the Sign of God will remain - a sign which He, Himself, hath placed within these realities. This sign will endure as long as is the wish of the Lord thy God, the Lord of the heavens and of the earth. If such be the blessings conferred on all created things, how superior must be the destiny of the true believer, whose existence and life are to be regarded as the originating purpose of all creation. Just as the conception of faith hath existed from the beginning that hath no beginning, and will endure till the end that hath no end, in like manner will the true believer eternally live and endure. His spirit will everlastingly circle round the Will of God. He will last as long as God, Himself, will last. He is revealed through the Revelation of God, and is hidden at His bidding. It is evident that the loftiest mansions in the Realm of Immortality have been ordained as the habitation of them that have truly believed in God and in His signs. Death can never invade that holy seat. Thus have We entrusted thee with the signs of Thy Lord, that thou mayest persevere in thy love for Him, and be of them that comprehend this truth.

Thou hast asked Me whether man, as apart from the Prophets of God and His chosen ones, will retain, after his physical death, the self-same individuality, personality, consciousness, and understanding that characterize his life in this world. If this should be the case, how is it, thou hast observed, that whereas such slight injuries to his mental faculties as fainting and severe illness deprive him of his understanding and consciousness, his death, which must involve the decomposition of his body and the dissolution of its elements, is powerless to destroy that understanding and extinguish that consciousness? How can any one imagine that man's consciousness and personality will be maintained, when the very instruments necessary to their existence and function will have completely disintegrated?  

Know thou that the soul of man is exalted above, and is independent of all infirmities of body or mind. That a sick person showeth signs of weakness is due to the hindrances that interpose themselves between his soul and his body, for the soul itself remaineth unaffected by any bodily ailments. Consider the light of the lamp. Though an external object may interfere with its radiance, the light itself continueth to shine with undiminished power. In like manner, every malady afflicting the body of man is an impediment that preventeth the soul from manifesting its inherent might and power. When it leaveth the body, however, it will evince such ascendancy, and reveal such influence as no force on earth can equal. Every pure, every refined and sanctified soul will be endowed with tremendous power, and shall rejoice with exceeding gladness. 

Consider the lamp which is hidden under a bushel. Though its light be shining, yet its radiance is concealed from men. Likewise, consider the sun which hath been obscured by the clouds. Observe how its splendor appeareth to have diminished, when in reality the source of that light hath remained unchanged. The soul of man should be likened unto this sun, and all things on earth should be regarded as his body. So long as no external impediment interveneth between them, the body will, in its entirety, continue to reflect the light of the soul, and to be sustained by its power. As soon as, however, a veil interposeth itself between them, the brightness of that light seemeth to lessen. 

Consider again the sun when it is completely hidden behind the clouds. Though the earth is still illumined with its light, yet the measure of light which it receiveth is considerably reduced. Not until the clouds have dispersed, can the sun shine again in the plenitude of its glory. Neither the presence of the cloud nor its absence can, in any way, affect the inherent splendor of the sun. The soul of man is the sun by which his body is illumined, and from which it draweth its sustenance, and should be so regarded. 

Consider, moreover, how the fruit, ere it is formed, lieth potentially within the tree. Were the tree to be cut into pieces, no sign nor any part of the fruit, however small, could be detected. When it appeareth, however, it manifesteth itself, as thou hast observed, in its wondrous beauty and glorious perfection. Certain fruits, indeed, attain their fullest development only after being severed from the tree.

Source: ibid. LXXX, pp. 153-55.

And now concerning thy question regarding the soul of man and its survival after death. Know thou of a truth that the soul, after its separation from the body, will continue to progress until it attaineth the presence of God, in a state and condition which neither the revolution of ages and centuries, nor the changes and chances of this world, can alter. It will endure as long as the Kingdom of God, His sovereignty, His dominion and power will endure. It will manifest the signs of God and His attributes, and will reveal His loving kindness and bounty. The movement of My Pen is stilled when it attempteth to befittingly describe the loftiness and glory of so exalted a station. The honor with which the Hand of Mercy will invest the soul is such as no tongue can adequately reveal, nor any other earthly agency describe. Blessed is the soul which, at the hour of its separation from the body, is sanctified from the vain imaginings of the peoples of the world. Such a soul liveth and moveth in accordance with the Will of its Creator, and entereth the all-highest Paradise. The Maids of Heaven, inmates of the loftiest mansions, will circle around it, and the Prophets of God and His chosen ones will seek its companionship. With them that soul will freely converse, and will recount unto them that which it hath been made to endure in the path of God, the Lord of all worlds. If any man be told that which hath been ordained for such a soul in the worlds of God, the Lord of the throne on high and of earth below, his whole being will instantly blaze out in his great longing to attain that most exalted, that sanctified and resplendent station....The nature of the soul after death can never be described, nor is it meet and permissible to reveal its whole character to the eyes of men. The Prophets and Messengers of God have been sent down for the sole purpose of guiding mankind to the straight Path of Truth. The purpose underlying their revelation hath been to educate all men, that they may, at the hour of death, ascend, in the utmost purity and sanctity and with absolute detachment, to the throne of the Most High. The light which these souls radiate is responsible for the progress of the world and the advancement of its peoples. They are like unto leaven which leaveneth the world of being, and constitute the animating force through which the arts and wonders of the world are made manifest. Through them the clouds rain their bounty upon men, and the earth bringeth forth its fruits. All things must needs have a cause, a motive power, an animating principle. These souls and symbols of detachment have provided, and will continue to provide, the supreme moving impulse in the world of being. The world beyond is as different from this world as this world is different from that of the child while still in the womb of its mother. When the soul attaineth the Presence of God, it will assume the form that best befitteth its immortality and is worthy of its celestial habitation. Such an existence is a contingent and not an absolute existence, inasmuch as the former is preceded by a cause, whilst the latter is independent thereof. Absolute existence is strictly confined to God, exalted be His glory. Well is it with them that apprehend this truth. Wert thou to ponder in thine heart the behavior of the Prophets of God thou wouldst assuredly and readily testify that there must needs be other worlds besides this world. The majority of the truly wise and learned have, throughout the ages, as it hath been recorded by the Pen of Glory in the Tablet of Wisdom, borne witness to the truth of that which the holy Writ of God hath revealed. Even the materialists have testified in their writings to the wisdom of these divinely-appointed Messengers, and have regarded the references made by the Prophets to Paradise, to hell fire, to future reward and punishment, to have been actuated by a desire to educate and uplift the souls of men. Consider, therefore, how the generality of mankind, whatever their beliefs or theories, have recognized the excellence, and admitted the superiority, of these Prophets of God. These Gems of Detachment are acclaimed by some as the embodiments of wisdom, while others believe them to be the mouthpiece of God Himself. How could such Souls have consented to surrender themselves unto their enemies if they believed all the worlds of God to have been reduced to this earthly life? Would they have willingly suffered such afflictions and torments as no man hath ever experienced or witnessed?

Source: ibid. LXXXI, pp. 155-58.

Thou hast asked Me concerning the nature of the soul. Know, verily, that the soul is a sign of God, a heavenly gem whose reality the most learned of men hath failed to grasp, and whose mystery no mind, however acute, can ever hope to unravel. It is the first among all created things to declare the excellence of its Creator, the first to recognize His glory, to cleave to His truth, and to bow down in adoration before Him. If it be faithful to God, it will reflect His light, and will, eventually, return unto Him. If it fail, however, in its allegiance to its Creator, it will become a victim to self and passion, and will, in the end, sink in their depths. 

Whoso hath, in this Day, refused to allow the doubts and fancies of men to turn him away from Him Who is the Eternal Truth, and hath not suffered the tumult provoked by the ecclesiastical and secular authorities to deter him from recognizing His Message, such a man will be regarded by God, the Lord of all men, as one of His mighty signs, and will be numbered among them whose names have been inscribed by the Pen of the Most High in His Book. Blessed is he that hath recognized the true stature of such a soul, that hath acknowledged its station, and discovered its virtues. 

Much hath been written in the books of old concerning the various stages in the development of the soul, such as concupiscence, irascibility, inspiration, benevolence, contentment, Divine good-pleasure, and the like; the Pen of the Most High, however, is disinclined to dwell upon them. Every soul that walketh humbly with its God, in this Day, and cleaveth unto Him, shall find itself invested with the honor and glory of all goodly names and stations. 

When man is asleep, his soul can, in no wise, be said to have been inherently affected by any external object. It is not susceptible of any change in its original state or character. Any variation in its functions is to be ascribed to external causes. It is to these external influences that any variations in its environment, its understanding, and perception should be attributed. 

Consider the human eye. Though it hath the faculty of perceiving all created things, yet the slightest impediment may so obstruct its vision as to deprive it of the power of discerning any object whatsoever. Magnified be the name of Him Who hath created, and is the Cause of, these causes, Who hath ordained that every change and variation in the world of being be made dependent upon them. Every created thing in the whole universe is but a door leading into His knowledge, a sign of His sovereignty, a revelation of His names, a symbol of His majesty, a token of His power, a means of admittance into His straight Path.... 

Verily I say, the human soul is, in its essence, one of the signs of God, a mystery among His mysteries. It is one of the mighty signs of the Almighty, the harbinger that proclaimeth the reality of all the worlds of God. Within it lieth concealed that which the world is now utterly incapable of apprehending. Ponder in thine heart the revelation of the Soul of God that pervadeth all His Laws, and contrast it with that base and appetitive nature that hath rebelled against Him, that forbiddeth men to turn unto the Lord of Names, and impelleth them to walk after their lusts and wickedness. Such a soul hath, in truth, wandered far in the path of error.... 

Thou hast, moreover, asked Me concerning the state of the soul after its separation from the body. Know thou, of a truth, that if the soul of man hath walked in the ways of God, it will, assuredly, return and be gathered to the glory of the Beloved. By the righteousness of God! It shall attain a station such as no pen can depict, or tongue describe. The soul that hath remained faithful to the Cause of God, and stood unwaveringly firm in His Path shall, after his ascension, be possessed of such power that all the worlds which the Almighty hath created can benefit through him. Such a soul provideth, at the bidding of the Ideal King and Divine Educator, the pure leaven that leaveneth the world of being, and furnisheth the power through which the arts and wonders of the world are made manifest. Consider how meal needeth leaven to be leavened with. Those souls that are the symbols of detachment are the leaven of the world. Meditate on this, and be of the thankful. 

In several of Our Tablets We have referred to this theme, and have set forth the various stages in the development of the soul. Verily I say, the human soul is exalted above all egress and regress. It is still, and yet it soareth; it moveth, and yet it is still. It is, in itself, a testimony that beareth witness to the existence of a world that is contingent, as well as to the reality of a world that hath neither beginning nor end. Behold how the dream thou hast dreamed is, after the lapse of many years, re-enacted before thine eyes. Consider how strange is the mystery of the world that appeareth to thee in thy dream. Ponder in thine heart upon the unsearchable wisdom of God, and meditate on its manifold revelations.... 

Witness the wondrous evidences of God's handiwork, and reflect upon its range and character. He Who is the Seal of the Prophets hath said: "Increase my wonder and amazement at Thee, O God!" 

As to thy question whether the physical world is subject to any limitations, know thou that the comprehension of this matter dependeth upon the observer himself. In one sense, it is limited; in another, it is exalted beyond all limitations. The one true God hath everlastingly existed, and will everlastingly continue to exist. His creation, likewise, hath had no beginning, and will have no end. All that is created, however, is preceded by a cause. This fact, in itself, establisheth, beyond the shadow of a doubt, the unity of the Creator. 

Thou hast, moreover, asked Me concerning the nature of the celestial spheres. To comprehend their nature, it would be necessary to inquire into the meaning of the allusions that have been made in the Books of old to the celestial spheres and the heavens, and to discover the character of their relationship to this physical world, and the influence which they exert upon it. Every heart is filled with wonder at so bewildering a theme, and every mind is perplexed by its mystery. God, alone, can fathom its import. The learned men, that have fixed at several thousand years the life of this earth, have failed, throughout the long period of their observation, to consider either the number or the age of the other planets. Consider, moreover, the manifold divergencies that have resulted from the theories propounded by these men. Know thou that every fixed star hath its own planets, and every planet its own creatures, whose number no man can compute. 

O thou that hast fixed thine eyes upon My countenance! The Day Spring of Glory hath, in this Day, manifested its radiance, and the Voice of the Most High is calling. We have formerly uttered these words: "This is not the day for any man to question his Lord. It behoveth whosoever hath hearkened to the Call of God, as voiced by Him Who is the Day Spring of Glory, to arise and cry out: 'Here am I, here am I, O Lord of all Names; here am I, here am I, O Maker of the heavens! I testify that, through Thy Revelation, the things hidden in the Books of God have been revealed, and that whatsoever hath been recorded by Thy Messengers in the sacred Scriptures hath been fulfilled.'"

Source: ibid. LXXXII, pp. 158-63.

Consider the rational faculty with which God hath endowed the essence of man. Examine thine own self, and behold how thy motion and stillness, thy will and purpose, thy sight and hearing, thy sense of smell and power of speech, and whatever else is related to, or transcendeth, thy physical senses or spiritual perceptions, all proceed from, and owe their existence to, this same faculty. So closely are they related unto it, that if in less than the twinkling of an eye its relationship to the human body be severed, each and every one of these senses will cease immediately to exercise its function, and will be deprived of the power to manifest the evidences of its activity. It is indubitably clear and evident that each of these afore-mentioned instruments has depended, and will ever continue to depend, for its proper functioning on this rational faculty, which should be regarded as a sign of the revelation of Him Who is the sovereign Lord of all. Through its manifestation all these names and attributes have been revealed, and by the suspension of its action they are all destroyed and perish. 

It would be wholly untrue to maintain that this faculty is the same as the power of vision, inasmuch as the power of vision is derived from it and acteth in dependence upon it. It would, likewise, be idle to contend that this faculty can be identified with the sense of hearing, as the sense of hearing receiveth from the rational faculty the requisite energy for performing its functions. 

This same relationship bindeth this faculty with whatsoever hath been the recipient of these names and attributes within the human temple. These diverse names and revealed attributes have been generated through the agency of this sign of God. Immeasurably exalted is this sign, in its essence and reality, above all such names and attributes. Nay, all else besides it will, when compared with its glory, fade into utter nothingness and become a thing forgotten. 

Wert thou to ponder in thine heart, from now until the end that hath no end, and with all the concentrated intelligence and understanding which the greatest minds have attained in the past or will attain in the future, this divinely ordained and subtle Reality, this sign of the revelation of the All-Abiding, All-Glorious God, thou wilt fail to comprehend its mystery or to appraise its virtue. Having recognized thy powerlessness to attain to an adequate understanding of that Reality which abideth within thee, thou wilt readily admit the futility of such efforts as may be attempted by thee, or by any of the created things, to fathom the mystery of the Living God, the Day Star of unfading glory, the Ancient of everlasting days. This confession of helplessness which mature contemplation must eventually impel every mind to make is in itself the acme of human understanding, and marketh the culmination of man's development.

Source: ibid. LXXXIII, pp. 164-66.

Regard thou the one true God as One Who is apart from, and immeasurably exalted above, all created things. The whole universe reflecteth His glory, while He is Himself independent of, and transcendeth His creatures. This is the true meaning of Divine unity. He Who is the Eternal Truth is the one Power Who exerciseth undisputed sovereignty over the world of being, Whose image is reflected in the mirror of the entire creation. All existence is dependent upon Him, and from Him is derived the source of the sustenance of all things. This is what is meant by Divine unity; this is its fundamental principle. 

Some, deluded by their idle fancies, have conceived all created things as associates and partners of God, and imagined themselves to be the exponents of His unity. By Him Who is the one true God! Such men have been, and will continue to remain, the victims of blind imitation, and are to be numbered with them that have restricted and limited the conception of God. 

He is a true believer in Divine unity who, far from confusing duality with oneness, refuseth to allow any notion of multiplicity to becloud his conception of the singleness of God, who will regard the Divine Being as One Who, by His very nature, transcendeth the limitations of numbers. 

The essence of belief in Divine unity consisteth in regarding Him Who is the Manifestation of God and Him Who is the invisible, the inaccessible, the unknowable Essence as one and the same. By this is meant that whatever pertaineth to the former, all His acts and doings, whatever He ordaineth or forbiddeth, should be considered, in all their aspects, and under all circumstances, and without any reservation, as identical with the Will of God Himself. This is the loftiest station to which a true believer in the unity of God can ever hope to attain. Blessed is the man that reacheth this station, and is of them that are steadfast in their belief.

Source: ibid. LXXXIV, pp. 166-67. 

O My servants! It behoveth you to refresh and revive your souls through the gracious favors which, in this Divine, this soul-stirring Springtime, are being showered upon you. The Day Star of His great glory hath shed its radiance upon you, and the clouds of His limitless grace have overshadowed you. How high the reward of him that hath not deprived himself of so great a bounty, nor failed to recognize the beauty of his Best-Beloved in this, His new attire. 

Say: O people! The Lamp of God is burning; take heed, lest the fierce winds of your disobedience extinguish its light. Now is the time to arise and magnify the Lord, your God. Strive not after bodily comforts, and keep your heart pure and stainless. The Evil One is lying in wait, ready to entrap you. Gird yourselves against his wicked devices, and, led by the light of the name of the one true God, deliver yourselves from the darkness that surroundeth you. Center your thoughts in the Well-Beloved, rather than in your own selves. 

Say: O ye that have strayed and lost your way! The Divine Messenger, Who speaketh naught but the truth, hath announced unto you the coming of the Best-Beloved. Behold, He is now come. Wherefore are ye downcast and dejected? Why remain despondent when the Pure and Hidden One hath appeared unveiled amongst you? He Who is both the Beginning and the End, He Who is both Stillness and Motion, is now manifest before your eyes. Behold how, in this Day, the Beginning is reflected in the End, how out of Stillness Motion hath been engendered. This motion hath been generated by the potent energies which the words of the Almighty have released throughout the entire creation. Whoso hath been quickened by its vitalizing power, will find himself impelled to attain the court of the Beloved; and whoso hath deprived himself therefrom, will sink into irretrievable despondency. He is truly wise whom the world and all that is therein have not deterred from recognizing the light of this Day, who will not allow men's idle talk to cause him to swerve from the way of righteousness. He is indeed as one dead who, at the wondrous dawn of this Revelation, hath failed to be quickened by its soul-stirring breeze. He is indeed a captive who hath not recognized the Supreme Redeemer, but hath suffered his soul to be bound, distressed and helpless, in the fetters of his desires. 

O My servants! Whoso hath tasted of this Fountain hath attained unto everlasting Life, and whoso hath refused to drink therefrom is even as the dead. Say: O ye workers of iniquity! Covetousness hath hindered you from giving a hearing ear unto the sweet voice of Him Who is the All-Sufficing. Wash it away from your hearts, that His Divine secret may be made known unto you. Behold Him manifest and resplendent as the sun in all its glory. 

Say: O ye that are bereft of understanding! A severe trial pursueth you, and will suddenly overtake you. Bestir yourselves, that haply it may pass and inflict no harm upon you. Acknowledge the exalted character of the name of the Lord, your God, Who hath come unto you in the greatness of His glory. He, verily, is the All-Knowing, the All-Possessing, the Supreme Protector.

And now concerning thy question whether human souls continue to be conscious one of another after their separation from the body. Know thou that the souls of the people of Baha, who have entered and been established within the Crimson Ark, shall associate and commune intimately one with another, and shall be so closely associated in their lives, their aspirations, their aims and strivings as to be even as one soul. They are indeed the ones who are well-informed, who are keen-sighted, and who are endued with understanding. Thus hath it been decreed by Him Who is the All-Knowing, the All-Wise. 

The people of Baha, who are the inmates of the Ark of God, are, one and all, well aware of one another's state and condition, and are united in the bonds of intimacy and fellowship. Such a state, however, must depend upon their faith and their conduct. They that are of the same grade and station are fully aware of one another's capacity, character, accomplishments and merits. They that are of a lower grade, however, are incapable of comprehending adequately the station, or of estimating the merits, of those that rank above them. Each shall receive his share from thy Lord. Blessed is the man that hath turned his face towards God, and walked steadfastly in His love, until his soul hath winged its flight unto God, the Sovereign Lord of all, the Most Powerful, the Ever-Forgiving, the All-Merciful. 

The souls of the infidels, however, shall - and to this I bear witness - when breathing their last be made aware of the good things that have escaped them, and shall bemoan their plight, and shall humble themselves before God. They shall continue doing so after the separation of their souls from their bodies. 

It is clear and evident that all men shall, after their physical death, estimate the worth of their deeds, and realize all that their hands have wrought. I swear by the Day Star that shineth above the horizon of Divine power! They that are the followers of the one true God shall, the moment they depart out of this life, experience such joy and gladness as would be impossible to describe, while they that live in error shall be seized with such fear and trembling, and shall be filled with such consternation, as nothing can exceed. Well is it with him that hath quaffed the choice and incorruptible wine of faith through the gracious favor and the manifold bounties of Him Who is the Lord of all Faiths.... 

This is the Day when the loved ones of God should keep their eyes directed towards His Manifestation, and fasten them upon whatsoever that Manifestation may be pleased to reveal. Certain traditions of bygone ages rest on no foundations whatever, while the notions entertained by past generations, and which they have recorded in their books, have, for the most part, been influenced by the desires of a corrupt inclination. Thou dost witness how most of the commentaries and interpretations of the words of God, now current amongst men, are devoid of truth. Their falsity hath, in some cases, been exposed when the intervening veils were rent asunder. They themselves have acknowledged their failure in apprehending the meaning of any of the words of God. 

Our purpose is to show that should the loved ones of God sanctify their hearts and their ears from the vain sayings that were uttered aforetime, and turn with their inmost souls to Him Who is the Day Spring of His Revelation, and to whatsoever things He hath manifested, such behavior would be regarded as highly meritorious in the sight of God.... 

Magnify His Name, and be thou of the thankful. Convey My greetings to My loved ones, whom God hath singled out for His love, and caused them to achieve their objects. All glory be to God, the Lord of all worlds.
