देवयानमिदं प्राहुर् भूत्वा भूत्वानुपूर्वशः ।
आत्मयाज्युपशान्तात्मा ह्यात्मस्थो न निवर्तते ॥ ५५ ॥
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.
