The blessed Lord said: I taught this imperishable yoga to Vivasvan, he
told it to Manu, Manu proclaimed it to Ikshvaku.This,
handed down thus in regular succession, the royal sages knew. This yoga by long lapse of
time, has been lost here, Oh Arjuna.
That same ancient yoga has been today taught to thee by me,
for thou art my devotee and my friend. It is the supreme secret.
