The soul is never born nor does it die at any time. It has neither past nor future. It is unborn, ever existing, permanent and ancient.
Just as a man discards worn out clothes and puts on new clothes, the soul discards worn out bodies and wears new ones.
It is a fact that that which is born is certain to die and that the one which has died is bound to take birth. There is no need to worry for the unavoidable.
All created beings were unmanifest in the beginning, manifest themselves in the middle and become unmanifest again when they die in the end. If this is so then where is the need for lamentation?
