Mbh 1.92.3

“Yayati answered, ‘The wise, with the help of the Vedas and of Knowledge, having ascertained the visible universe to be illusory, instantly realises the Supreme Spirit as the sole existent independent essence. While they that devote themselves to Yoga meditation take time to acquire the same knowledge, for it is by practice alone that these latter divest themselves of the consciousness of quality. Hence the wise attain to salvation first. Then again if the person devoted to Yoga find not sufficient time in one life to attain success, being led astray by the attractions of the world, in his next life he is benefited by the progress already achieved, for he devoteth himself regretfully to the pursuit of success. But the man of knowledge ever beholdeth the indestructible unity, and, is, therefore, though steeped in worldly enjoyments, never affected by them at heart. Therefore, there is nothing to impede his salvation. He, however, who faileth to attain to knowledge, should yet devote himself to piety as dependent on action (sacrifices &c.). But he that devoteth himself to such piety, moved thereto by desire of salvation, can never achieve success. His sacrifices bear no fruit and partake of the nature of cruelty. Piety which is dependent on action that proceedeth not from the desire of fruit, is, in case of such men Yoga itself.’
