7.15.55

देवयानमिदं प्राहुर्भूत्वा भूत्वानुपूर्वश: । आत्मयाज्युपशान्तात्मा ह्यात्मस्थो न निवर्तते ॥ ५५ ॥

deva-yanam idam prahur bhutva bhutvanupurvasah atma-yajy upasantatma hy atma-stho na nivartate

deva-yanam
the process of elevation known as deva-yana
idam
on this (path)
prahuh
it is said
bhutva bhutva
having repeated birth
anupurvasah
consecutively
atma-yaji
one who is eager for self-realization
upasanta-atma
completely free from all material desires
hi
indeed
atma-sthah
situated in his own self
na
not
nivartate
does return.

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.
