Mbh 13.145.8

"'"'Maheswara said, "Through the Vedas, the limits have been assigned of all the acts of human beings. Those men that conduct themselves according to the authority of the Vedas, are seen (in their next lives) to become devoted to the observance of vows. Those men, however, who having become subject to the sway of folly accept unrighteousness for its reverse, become destitute of vows, transgress all restraints, and come to be regarded as Brahmarakshasas. Indeed, it is these men that become unmindful of the Homa, that never utter the Vashat and other sacred Mantras, and that come to be regarded as the lowest and vilest of men. Thus, O goddess, have I explained to thee the entire ocean of duties in respect of human beings for the sake of removing thy doubts, not omitting the sins of which they become guilty."'"'"
