Mbh 12.273.2a

"'Bhishma said, "Thou knowest all duties. This question that thou askest is only for confirmation of thy conclusions. Listen now to Emancipation, and Renunciation, and Sin, and Virtue to their very roots. Perceiving any one of the five objects (viz., form, taste, scent, sound, and touch), desire runs after it at first. Indeed, obtaining them within the purview of the senses, O chief of Bharata's race, desire or aversion springs up.[1295] One, then, for the sake of that object (i.e., for acquisition of what is liked and avoidance of what is disliked) strives and begins acts that involve much labour. One endeavours one's best for repeatedly enjoying those forms and scents (and the three other objects of the remaining three senses) that appear very agreeable. Gradually, attachment, and aversion, and greed, and errors of judgment arise. The mind of one overwhelmed by greed and error and affected by attachment and aversion is never directed to virtue. One then begins with hypocrisy to do acts that are good. Indeed, with hypocrisy one then seeks to acquire virtue, and with hypocrisy one likes to acquire wealth. When one succeeds, O son of Kuru's race, in winning wealth with hypocrisy, one sets one's heart to such acquisition wholly. It is then that one begins to do acts that are sinful, notwithstanding the admonitions of well-wishers and the wise, unto all which he makes answers plausibly consistent with reason and conformable to the injunctions of the scriptures. Born of attachment and error, his sins, of three kinds, rapidly increase, for he thinks sinfully, speaks sinfully, and acts sinfully. When he fairly starts on the way of sin, they that are good mark his wickedness. They, however, that are of a disposition similar to that of the sinful man, enter into friendship with him. He succeeds not in winning happiness even here. Whence then would he succeed in winning happiness hereafter? It is thus that one becomes sinful.
