But as to the root of the Other Side in comparison with that of the Holy Side, it is almost forbidden even to ask if there is any equivalence between them (God forbid). For the root of the good is the one, unified, primordial, eternal Master, blessed be He and blessed be His Name for ever and ever. On the other hand, the root of the evil Other Side is merely something newly brought into being whose entire existence depends only on the fact that this is what was willed by the Supreme Will. Had He not willed it, it would not have existed, and if He did not want it, it would not endure. When He no longer wants it, it will no longer exist, but “He will consume death for ever and the Lord God will wipe the tears from all faces” (Isaiah 25:8).
