From then on, he continually acquires and reaches levels of sanctity that are part of the plan of creation and are present in the Ein Sof [the Infinite]. These [levels of sanctity] assist the person in transforming the selfish desire to receive that is embedded in him into a desire to give, to the point that he becomes one who receives only in order to give satisfaction to his Maker rather than to benefit himself.
In this way, a person equates his own form to [that of] his Maker. For receiving for the sake of giving to others is considered the purest form of giving. (This is related to what is stated in Kiddushin 7a: If a woman gives a gift to an important man, she receives benefit from the fact that he consents to accept a gift from her. That benefit is adequate to be considered the exchange that is legally required for them to be married.
The fact that he accepts the gift in order for her to benefit from the fact that she gave it to him is considered a complete gift to her.) The person then achieves a complete bond with God. For a spiritual bond is nothing other than an equating of form. To paraphrase a statement of the Sages: “How can one cleave to God?
Rather, cleave to His attributes” (based on Sota 14a). That is how a person can become worthy to receive all of the good, pleasantness, and softness that was in the plan of creation.
