“[S]ince the essence of the soul is but a will to bestow, and all its manifestations and possessions are fulfillments of that will to bestow (…) therefore it is immortal and irreplaceable. The soul, with all its manifestations is eternal and exists forever. Absence does not apply to them upon the departure of the body. On the contrary, the absence of the corrupted form of the body, greatly strengthens it, thus enabling it to rise to the Heavens. Thus we have clearly shown that the persistence in no way depends upon the concepts it has acquired, as philosophers claim, but its eternality is in its very essence, meaning in its will to bestow, which is its essence. And the concepts it acquires are its reward, not its essence.”
