Thou has asked concerning the spirit and its immortality after its departure. Know thou that at the time of its translation it ascends and ascends until it reaches the presence of God, clothed in a temple (body) which will not become subject to the changes wrought by ages and cycles, nor by the contingencies of the world, nor the emanations thereof.
It will continue to exist through the eternity of the Kingdom of God -- its sovereignty, its dominion, its potency. From it will appear the signs of God and his qualities, the providence of God and his bestowal. Verily the pen is unable to move in a befitting manner in explaining this truth -- its exaltation and loftiness.
The hand of mercy shall cause it to enter into men's minds, though it cannot be grasped through any explanation, nor be described by those means which are available in the world.
Blessed is the spirit which abandons the body, previously sanctified and freed from the doubts of the nations. Verily, it moves in the atmosphere of the will of its Lord, and it enters into the supreme paradise. It is welcomed by the angels of the Most High. It associates with the prophets of God, and his chosen ones, and it converses with them, and relates to them those events which have happened to it in the path of God, the Lord of both worlds.
Were one to become informed of that which is pre ordained for the spirit in the worlds of God, the Lord of the throne and the earth, he would become immediately enkindled with the fire of yearning for this impregnable, exalted, holy, and most glorious state of being. (Words of ‘Abdu’l-Baha, from ‘Diary of Mirza Ahmad Sohrab’, February, 1914; Star of the West, vol. 7, no. 19, March 2, 1917)
