THE ANSWER: Firstly, the bodies of living creatures are doomed to annihilation and death in this world because of an imbalance between what is taken in and what is expended. From childhood until maturity much is taken in, and after that what is expended increases; the balance is spoilt, and the body dies. In the world of eternity, however, the particles of the body remain constant and are not subject to composition and dissolution, or else the balance remains constant. [^1] Like a closed circle or perpetual motion, a living creature’s body becomes eternal together with the machine of bodily life’s functioning for pleasure. Although in this world eating and drinking and sexual relations arise from need and perform various functions, delights and pleasures have been placed within them as an immediate wage for the duty performed, and these are superior to other pleasures. Since in this abode of sorrows eating and sexual relations are the means to so many wonderful and various pleasures, certainly in Paradise, which is the abode of pleasure and bliss, those pleasures will take on a sublime form. The recompense of the duties pertaining to the hereafter performed here will also be added to them as pleasure, and they will be augmented by worldly needs which have taken the form of agreeable, otherworldly appetites, so will become an all-embracing, living source of pleasure worthy of Paradise and suitable to eternity. Indeed, according to the meaning of the verse,

[^1]:In this world, the bodies of humans and animals are like guesthouses, barracks, and schools for particles. The lifeless particles enter them and acquire worthiness to be particles for the everlasting realm, which is living, then they leave them. In the hereafter, however, according to the verse, “The Abode of the Hereafter, that is life indeed”(29:64), the light of life is general. There is no necessity for that travelling, drill, and instruction in order to be illuminated. Particles will remain constant as permanent fixtures.

And what is the life of this world but amusement and play? But indeed the Abode of the hereafter, that is life indeed,(29:64)

substances and matters which are inanimate and without consciousness and life in the abode of this world, there will be living and conscious. Like human beings and animals here, the trees and stones there will understand commands and carry them out. If you tell a tree to bring you such-and-such a fruit, it will bring it. And if you tell such-and-such a stone to come, it will come. Since stones and trees will take on this elevated form, it surely necessitates that, together with preserving their bodily realities, eating, drinking, and sexual relations also will take on a form higher than their worldly form, higher to the degree that Paradise is higher than this world.
