The Sin Of The Soul

Question: It is written that a soul that has sinned will surely die. How is it possible to understand this?

Answer: A soul is an altruistic desire, a desire to bestow, to give pleasure, a desire to connect with others.

If it sins, in other words, if it begins to receive for itself and not to bestow to others or to the Creator, then it “dies,” meaning that it transforms into an egoistic fragment that must be reborn and attached with the single general soul again. This is called “revival of the dead.”
