"Kapila said, 'Whatever the Sastras according to which one performs the acts one feels inclined to do, the ordinances laid down in it for regulating those acts never become fruitless. Whatever again the school of opinion according to which one may conduct oneself, one is sure to attain to the highest end by only observing the duties of self-restraint of Yoga. Knowledge assists that man in crossing (this interminable river of life and death) who pursues knowledge. That conduct, however, which men pursue after deviating from the path of knowledge, afflicts them (by subjecting them to the evils of life and death). It is evident that ye are possessed of knowledge and dissociated from every worldly object that may produce distress. But have any of you at any time succeeded in acquiring that knowledge in consequence of which everything is capable of being viewed as identical with one Universal Soul? Without a correct apprehension of the scriptures, some there are, fond only of disputation, who, in consequence of being overwhelmed by desire and aversion, become the slaves of pride and arrogance. Without having correctly understood the meaning of scriptural declarations, these robbers of the scriptures, these depredators of Brahma, influenced by arrogance and error, refuse to pursue tranquillity and practise self-restraint. These men behold fruitlessness on every side, and if (by chance) they succeed in obtaining the puissance of knowledge they never impart it to others for rescuing them. Made up entirely of the quality of Tamas, they have Tamas only for their refuge. One becomes subject to all the incidents of that nature which one imbibes. Accordingly, of him who hath Tamas for his refuge, the passions of envy, lust, wrath, pride, falsehood, and vanity, continually grow, for one's qualities have one's nature for their spring. Thinking in this strain and beholding these faults (through the aid of instructions secured from preceptors), Yatis, who covet the highest end, betake themselves to Yoga, leaving both good and ill.'
