Mbh 12.292.1a

"'"Parasara said, 'That man who, having obtained this car, viz., his body endued with mind, goes on, curbing with the reins of knowledge the steeds represented by the objects of the senses, should certainly be regarded as possessed of intelligence. The homage (in the form of devotion to and concentrated meditation on the Supreme) by a person whose mind is dependent on itself and who has cast off the means of livelihood is worthy of high praise,--that homage, namely, O regenerate one, which is the result of instructions received from one who has succeeded in transcending acts but not obtained from the mutual discussion of men in the same state of progress.[1506] Having obtained the allotted period of life, O king, with such difficulty, one should not diminish it (by indulgence of the senses). On the other hand, man should always exert, by righteous acts for his gradual advancement.[1507] Among the six different colours that Jiva attains at different periods of his existence, he who falls away from a superior colour deserves obloquy and censure. Hence, one that has attained to the result of good acts should conduct oneself in such a way as to avoid all acts stained by the quality of Rajas.[1508] Man attains to a superior colour by righteous acts. Unable to acquire a superior hue, for such acquisition is extremely difficult, a person, by doing sinful acts only slays himself (by sinking into hell and falling down into an inferior colour). All sinful acts that are committed unconsciously or in ignorance are destroyed by penances. A sinful act, however, that is committed knowingly, produces much sorrow. Hence, one should never commit sinful acts which have for their fruit only sorrow. The man of intelligence would never do an act that is sinful in character even if it leads to the greatest advantage, just as a person that is pure would never touch a Chandala.[1509] How miserable is the fruit I see of sinful acts!
