Vedic Theology: The soul is a particle of that all-pervading principle, the Universal Intellect, or Soul of the World, detached for a while from its primitive source; and placed in connection with the bodily frame, but destined, by an inevitably as rivers run back to be lost in the ocean from whence they arose.
The Bible: As the cloud is consumed and vanisheth away, so he that goeth down to the grave shall come up no more. ([Job 7 : 9].) They are dead, they shall not live; they are deceased, they shall not rise; therefore hast thou visited and destroyed them, and made all their memory to perish. ([Isa. 26 : 14].) For the living know that they shall die, but the dead know not anything, neither have they any more a reward, for the memory of them is forgotten. Whatsoever thy hand findeth to do, do it with thy might, for there is no work, nor device, nor knowledge, nor wisdom in the grave whither thou goest. ([Eccl. 9 : 5, 10].) For that which befalleth the sons of men befalleth beasts, even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; so that a man hath no pre-eminence above a beast; for all is vanity. All go unto one place, all are of the dust and all turn to dust again. Who knoweth the spirit of man that goeth upward; and the spirit of the beast that goeth downward to the earth? ([Eccl. 3 : 19–22].) There (the grave) the wicked cease from troubling; and there the weary be at rest. (Vide [Job 3 : 11–22].)
Having thus successfully responded to the interrogatory, What is the soul? that is to say, the constituent thereof, let us now very briefly settle the locus in quo:
Plato: The soul is located in the brain.
Aristotle: The soul is located in the heart.
Heraclitus: The soul is located in the blood.
Epicurus: The soul is located in the chest.
Critios: The soul is located in the blood.
Sommering: The soul is located in the ventricles.
Kant: The soul is located in the water contained in the ventricles.
