Vyas (Badarayan) recited Vedanta (sutras) after churning and researching the thought frame of the Samaveda.
He put up before the self (atman) as identical to indescribable Brahm.
He in invisible and the jiv wanders hither and thither in its delusions of self conceit.
By establishing the self as the Brahm he is in fact established one’s own self as worthy of worship and therefore remained unknown to the mysteries of loving devotion.
Churning of the Vedas could not obtain peace for him and he started scorching one and all in the heat of is ego.
The rod of maya always hung over his head and he suffered extremely because of the constant fear of the Yama, the god of death.
Having obtained knowledge from Narad, he recited Bhagvat and thus eulogised God.
Without surrender before the Guru none could get across (the world ocean).
