Question: If we say that everything comes from the Creator, does that mean that a person does not really exist at all?

Answer: The fact that everything comes from the Creator does not negate the existence of a person. A person is the sensing element.

As we study, the Kli (vessel) is the desire to receive delight from the Creator. The Creator fills the Kli with His presence.

All fulfillment that comes beyond what is necessary (everything that appears after the first stage of the four phases of the expansion of the direct light) arises from the sensation of the Creator, from the sensation of the Host Himself, rather than from what He has prepared for me to receive.

The Kli is the organ that perceives spiritual reality. Accordingly, the degree of the Creator’s concealment or revelation corresponds to the degree of emptiness (darkness) or fulfillment experienced within the spiritual vessel (Kli).
