“His life” refers to the light that is enclothed in the white, which is the vessels, as stated above. This light is also comprehended by us only in relation to the souls that receive from Atzilut, and not, God forbid, within the Divinity in and of itself, for that is the mystical meaning of “He,” as stated above.33"His life," the light, does not refer to His essence. Rather it is the manifestation of His essence that we are able to experience from our perspective.
This is similar to the light of the sun, in contrast to the sun itself. We perceive the radiance of the sun, indicating to us that the sun itself is present. We do not directly encounter the body of the sun, analogous to the essence of God here. That is, when the three worlds of Beria, Yetzira, and Asiya ascend to Atzilut with the souls of people, the light they receive there is considered the light of Ḥokhma, which is called the “light of vitality.” It is from this perspective that we call the light “His life.”
