Dwelling in solitude, abstemious, speech, body and mind subdued, constantly fixed in meditation and yoga, taking refuge in dispassion, Having cast aside egoism, violence, arrogance, desire, wrath, covetousness, selfless and peaceful—he is fit to become the Eternal. Becoming the Eternal, serene in the Self, he neither grieveth nor desireth; the same to all beings, he obtaineth supreme devotion unto Me.
