Derekh Hashem, Part Three, On Divine Names and Witchcraft

Two levels of powers: We have already explained in the previous sections that the origin of all the creatures is the aggregate of all the ethereal forces arranged in a certain order with well-known divisions; and they unfold from them in the gradation of physical entities according to their species. We also explained the matter of the powers of evil, from which all of the physical evils unfold. We also explained that the main essence of that which is created is the ethereal roots; and that which is physical is only an extension of what is rooted and established there. And it is there that what is fitting to be extended is arranged and extended according to the true essence of their existence - and their content according to what is fitting to be in their roots and in their branches. So the Supreme Wisdom extended the things with an unfolding that extends and moves content from one form to another until they are connected and limited by this physical form. And above all the physical things is their chain of roots - one above the other - until the first forces. And each one stands in its place, and exists on its level and within its boundaries that the Creator, may He bless, designed for it, such that it does not leave them. And all of the roots influence their branches according to the unfolding, without their having to leave their natural boundaries at all.
