śuklakṛṣṇe gatī hyete jagataḥ śāśvate mate |
ekayā yātyanāvṛttimanyayāvartate punaḥ || 26 ||

The bright and the dark, these two paths, are regarded to be the eternal (two paths) of the universe. By the one, (one) goeth never to return; by the other, one (going) cometh back. Knowing these two paths, O son of Pritha, no devotee is deluded. Therefore, at all times, be endued with devotion, O Arjuna. The meritorious fruit that is prescribed for the (study of the) Vedas, for sacrifices, for ascetic austerities and for gifts, a devotee knowing all this (that hath been said here), attaineth to it all, and (also) attaineth the Supreme and Primeval seat.'
