Wars between Suras and Asuras : Bhfgu curses Visnu - Verse 156-160

He said thus : “O Brahmana, such an observance ( of a vow) as this has been performed by you alone and not by anyone (so far). Hence you will excel all Devas in penance, intellect, learning, strength and brilliance. O son of Bhrgu, whatever I possess by way of the esoteric secret of Yajfias, Upani$ads etc. along with their ancillaries and esoteric secrets (Rahasya) will be known to you alone, from the beginning to the end and not to anyone else. Thereby you will become an excellent Brahmana surpassing all”. Thus granting the boons one after the other, to the son of Bhrgu, he granted him invincibility, lordship of wealth and immunity from death. On attaining these boons, Kavya became exhilarated. Hairs on his body stood on their end due to excessive pleasure.
