In the second and third chapters of the Gita, Sri Krishna blessed Arjuna with a few glimpses of Yogic light. In the present chapter, he blesses Arjuna with a flood of spiritual light. He widely and openly reveals the secrets of Yoga. Hard is it for Arjuna to believe that Sri Krishna taught Vivaswan (the Sun-God) this eternal Yoga. Vivaswan offered it to his son Manu, and Manu imparted it to his son Ikshwaku; from him it was handed down to the royal Rishis. Long before Sri Krishna’s birth, Vivaswan saw the light of day. Naturally Sri Krishna’s declaration would throw Arjuna into the sea of confusion.
The eternal mystery of reincarnation is now being revealed. Says Krishna: “Arjuna, you and I have passed through countless births. I know them all, your memory fails you. Although I am birthless and deathless and the Supreme Lord of all beings, I manifest myself in the physical universe through my own Maya, keeping my Prakriti (Nature) under control.”
