Gravity of import

"In former days, having placed the four Vedas on one side and the Bharata on the other, these were weighed in the balance by the celestials assembled for that purpose. And as the latter weighed heavier than the four Vedas with their mysteries, from that period it hath been called in the world Mahabharata (the great Bharata). Being esteemed superior both in substance and gravity of import it is denominated Mahabharata on account of such substance and gravity of import. He that knoweth its meaning is saved from all his sins.
