Therefore, the four levels that correspond to the Tetragrammaton, the four-letter name of God, which are Ḥokhma, Bina, Tiferet, and Malkhut, are necessary. The first level, called Ḥokhma, actually contains the entirety of the emanated being, both light and vessel. It incorporates the full will to receive together with the entirety of the light within it, which is called the “light of wisdom,” also called the “light of vitality,” as it comprises all the light of the life force that is in the emanated being enclothed in its vessel. Yet this first level is categorized as entirely light and its vessel is barely recognizable, since the vessel is mingled with the light and subsumed in it like a candle in the presence of a torch.
