In plain words
From not knowing whom alone men come to experience saṃsāra, and from knowing whom alone comes ultimate liberation—this the Upanishads declare with absolute clarity. That primal teacher turned inward, the southern-facing Lord, I hold in my heart.
Close to the Sanskrit
From ignorance of whom alone arises the experience of saṃsāra for men, and from knowledge of whom alone comes liberation—thus clearly declares the crown of the Vedas; that primal teacher, turned inward, whose face is to the south, I contemplate.
