On Vasanas pure and impure: To which Vasistha replied thus, "Oh Rama of marvellous qualities, it is through one s efforts alone and none else that the Brahmic seat can be mastered. Now the hosts of Vasanas may be divided under two heads, vis., the pure and the impure. Of these two, those alone which were generated by him in his many lives will cling to him (in his future births). Should the pure ones cling to him, he will easily attain the immaculate Brahmic Seat through them; but in the case of the impure Vasanas, pains will be generated. You should, oh Rama, even through dint of painful efforts, avoid these impure ones. Through the two ordained paths of good and evil, the current of Vasanas swells enormously. May you, after straining all your nerves in the cultivation of Brahma vidya (Brahmic science), liberate yourself from the impure Vasanas and rest firmly in the (pure) Vasanas appertaining to the beneficent Reality. You should, through your equal vision over all and your own efforts, play fully check the lad of mind from getting into the impure Vasanas and make it associate with the pure ones. If after annihilating the many impure ones which are the products of the many previous births, you should make the pure ones dawn now, then they will conduce to your (future) efforts..."
