deva-yanam idam prahur
hy atma-stho na nivartate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This gradual process of elevation for self-realization is meant for those who are truly aware of the Absolute Truth. After repeated birth on this path, which is known as deva-yana, one attains these consecutive stages. One who is completely free from all material desires, being situated in the self, need not traverse the path of repeated birth and death.
