According to all three systems, the transmigration of the soul through different bodies is an evil resulting from desire. As long as the soul wishes anything, it will continue to migrate and to suffer. When it gathers itself up into calm insight, it ceases to wander and finds repose. The _Vedanta_ or _Mimansa_ is supposed to be referred to in Manu.[67] _Mimansa_ means "searching." In its logical forms it adopts the method so common among the scholastics, in first stating the question, then giving the objection, after that the reply to the objection, and lastly the conclusion. The first part of the Mimansa relates to worship and the ceremonies and ritual of the Veda. The second part teaches the doctrine of Brahma. Brahma is the one, eternal, absolute, unchangeable Being. He unfolds into the universe as Creator and Created. He becomes first ether, then air, then fire, then water, then earth. From these five elements all bodily existence proceeds. Souls are sparks from the central fire of Brahma, separated for a time, to be absorbed again at last. Brahma, in his highest form as Para-Brahm, stands for the Absolute Being. The following extract from the Sáma-Veda (after Haug's translation) expresses this: "The generation of Brahma was before all ages, unfolding himself evermore in a beautiful glory; everything which is highest and everything which is deepest belongs to him. Being and Not-Being are unveiled through Brahma." The following passage is from a Upanishad, translated by Windischmann:-- "How can any one teach concerning Brahma? he is neither the known nor the unknown. That which cannot be expressed by words, but through which all expression comes, this I know to be Brahma. That which cannot be thought by the mind, but by which all thinking comes, this I know is Brahma. That which cannot be seen by the eye, but by which the eye sees, is Brahma. If thou thinkest that thou canst know it, then in truth thou knowest it very little. To whom it is unknown, he knows it; but to whom it is known, he knows it not." This also is from Windischmann, from the Kathaka Upanishad: "One cannot attain to it through the word, through the mind, or through the eye. It is only reached by him who says, 'It is! It is!' He perceives it in its essence. Its essence appears when one perceives it as it is." The old German expression _Istigkeit_, according to Bunsen, corresponds to this. This also is the name of Jehovah as given to Moses from the burning bush: "And God said unto Moses, I AM THE I AM. Thus shalt thou say unto the children of Israel, I AM hath sent me unto you." The idea is that God alone really exists, and that the root of all being is in him. This is expressed in another Upanishad: "HE WHO EXISTS is the root of all creatures; he WHO EXISTS is their foundation, and in him they rest."
