Srimad Bhagavatam Canto 10, Chapter 85, Text 46

SB 10.85.46

sadhy asman isitavyesa
 nispapan kuru nah prabho
puman yac chraddhayatisthams
 codanaya vimucyate
O Lord of all subordinate creatures, please tell us what to do and thus free us of all sin. One who faithfully executes Your command, O master, is no longer obliged to follow the ordinary Vedic rites.
The acaryas explain Bali’s thoughts as follows. Reflecting on the possibility that his request for immediate deliverance may have been too bold, Bali Maharaja considers that first he will need to become sufficiently purified. In any case, he thinks, Lord Krsna and Lord Balarama must have come to him for some specific purpose; if he can receive the Lords’ order and carry it out, that will be his best opportunity for purification. Indeed, as Bali states, a devotee acting under the Personality of Godhead’s instruction need no longer follow the sacrificial injunctions and prohibitions of the Vedas.
