From ‘At the feet of Bhagavan’ by T K Sundaresa Iyer

….Bhagavan remarked that this is just what the look of Grace from a Jnani does. One look into a soul, and the whole tree of past tendencies and prejudices (vasana), gathered up through long cycles of past births is burned up and decays away. Then the reality of the Self is experienced. Thus He explained …..the supreme Jnana obtained with the touch of the Saint can never be won through the study of any number of Scriptures, or by any store of good deeds, or by any other spiritual practices and efforts.
