Our self (Soul), as a form of God's joy, is deathless. For his joy is amritham, eternal bliss. We know that the life of a Soul, which is finite in its expression and infinite in its principle, must go through the portals of death in its journey to realize the infinite.
There is in general good reason to suppose that in several respects the gods could all benefit from instruction by us human beings. We humans are - more humane.
Even the lowest of the low have the Atman (Soul) inside, which never dies and never is born, immortal, without beginning or end, the all pure, omnipotent and omnipresent Atman!
The universe is large and we are tiny, without the need for further religious superstructure. One can have so-called spiritual moments without belief in the spirit.
