It is difficult to feel and understand what a soul is, yet Kabbalists tell us that a soul is a part of the Creator, who is the quality of bestowal. When the desire to receive pleasure assumes the form of bestowal, it begins to work as a bestowing desire. As a result, it feels similarity with the Creator, as though it is a part of Him.
Every time we feel a change within, we have a new and different soul. During each of our actions of merging with the Light, twenty-five new spiritual Partzufim, or souls, are born. So how is it possible to identify ourselves in the spiritual world? In this material world we identify ourselves by everything we currently perceive as our own, such as by our body parts (the arms, legs, head, and so on). As long as we’re alive, the same body will remain with us now and tomorrow, and the next day, and so forth.
However, what is “ours” in the spiritual world? What remains with us from the previous state if we constantly receive ten new Sefirot and a new depth (Aviut) of desire, with new qualities, a new screen, and new Light? Is there something that remains in order to feel that it’s “us” who advance instead of the birth of some other soul?
The truth is that in spirituality, every day and every instant, you are a new person. Nothing ever remains with you from the past. It is contrary to our material life. In spirituality, everything is constantly renewed, except the initial point in the heart.
