Śaṅkarācārya's commentary

Thy birth is later, in the house of Vasudeva; Vivasvat's (Āditya's) birth is prior, in the beginning of evolution; how, then, am I to reconcile the statements that Thou taughtest this Yoga in the beginning to Vivasvat, and that Thou, the self-same person, hast now taught it to me?
