In contrast, the essence of the soul is a desire to give, and all of its experiences and everything it acquires fill this desire to give. It remains eternally in first stage and in the future third stage. It is, therefore, immortal and permanent. It and everything it acquires are eternal, living forever. They are not at all affected by the non-being of the body’s death. On the contrary, the absence of the defective body’s form [after death] greatly strengthens the soul, allowing it to ascend to the heights of the Garden of Eden.
