Accordingly, the light and vessel in the second level are completely different from those of the first level, as the vessel of the second level has the will to give, while the light within it differentiates into the light of giving, a light that emanates from the power of the cleaving of the emanated being to the Emanator. That is, the will to give that is awakened within the vessel brings about the equating of its form with that of the Emanator, and the equating of form is the way an entity cleaves to another in the spiritual realm, as stated below.
