Mbh 13.18.1d

He is always the great dispenser and ordainer in the matter of the happiness and sorrow of all living creatures. That illustrious Deity is incapable of being comprehended in thought, word, or deed. O son, O thou that are the best of warriors (through the grace of Mahadeva), there is none that is equal to me in learning."--After this, Vasudeva, that foremost of all intelligent men, once more said,--"Mahadeva of golden eyes was gratified by me with my penances. Gratified with me, O Yudhishthira, the illustrious Deity said unto me,--'Thou shalt, O Krishna, through my grace, become dearer to all persons than wealth which is coveted by all. Thou shalt be invincible in battle. Thy energy shall be equal to that of Fire.' Thousands of other boons Mahadeva gave unto me on that occasion. In a former incarnation I adored Mahadeva on the Manimantha mountain for millions of years. Gratified with me, the illustrious Deity said unto me these words:--'Blessed be thou, do thou solicit boons as thou wishest. Bowing unto him with a bend of my head, I said these words,--'If the puissant Mahadeva has been gratified with me, then let my devotion to him be unchanged, O Isana! Even this is the boon that I solicit.'--The great God said unto me,--'Be it so'--and disappeared there and then."
