Mbh 5.45.1c

Truth (Brahman) resides in him who knoweth Brahman as vested with attributes. It dwelleth more completely in him who knoweth Brahman as divested of attributes. Listen now to something else from me. This high and celebrated philosophy should be taught (to disciples). All other systems are only a farrago of words. The whole of this (universe) is established in this Yoga-philosophy. They that are acquainted with it are not subjected to death. O king, one cannot, by Work, however well-accomplished, attain to Truth (Brahman). The man that is destitute of knowledge even if he poureth homa libations or performeth sacrifices, can never, by Work, O king, attain to immortality (emancipation). Nor doth he enjoy great happiness at the end. Restraining all the external senses and alone, one should seek Brahman. Giving up Work, one should not exert mentally. One should also (while thus engaged) avoid experiencing joy at praise or anger at blame. O Kshatriya, by conducting himself in this way according to the successive steps indicated in the Vedas, one may, even here, attain to Brahman. This, O learned one, is all that I tell thee.’”
