The entire material of creation is desire created by the Creator, who also sends the Light that fulfills the desire. Man is the correct correlation between the Light and the desire, and since man’s actions most always come from desire, his actions are therefore determined by the Creator.
However, if we aspire to reach connection between us by helping each other, acting “against the Creator” who created this separation between us, it truly becomes our own action.
The quality which the creature acquires by this action is called “a soul.” This soul doesn’t initially exist in us, and the Creator cannot give us a soul. Rather, a soul is created by our desire to connect above our egoism.
All states descending from the World of Infinity to our world (the last stage) exist in us in the form of records, which can be realized only by our efforts towards unification. Our descent resulted in separation, and our ascension is the action of moving towards unification.
