Bahá’u’lláh tells us that the life in the flesh is but the embryonic stage of our existence, and that escape from the body is like a new birth through which the human spirit enters on a fuller, freer life. He writes:—
“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 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.”—Gleanings from the Writings of Bahá’u’lláh.
Similarly, ‘Abdu’l-Bahá writes:—
“The mysteries of which man is heedless in the earthly world, those will he discover in the heavenly world, and there will he be informed of the secrets of the truth; how much more will he recognize or discover persons with whom he has been associated. Undoubtedly the holy souls who find a pure eye and are favored with insight will, in the kingdom of lights, be acquainted with all mysteries, and will seek the bounty of witnessing the reality of every great soul. They will even manifestly behold the Beauty of God in that world. Likewise will they find all the friends of God, both those of the former and recent times, present in the heavenly assemblage.”
“The difference and distinction between men will naturally become realized after their departure from this mortal world. But this distinction is not in respect to place, but in respect to the soul and the conscience. For the Kingdom of God is sanctified (or free) from time and place; it is another world and another universe. And know thou for a certainty that in the divine worlds the spiritual beloved ones will recognize one another, and will seek union with each other, but a spiritual union. Likewise a love that one may have entertained for anyone will not be forgotten in the world of the Kingdom, nor wilt thou forget there the life that thou hadst in the material world.”
