D.: Is the study of science, psychology, physiology, philosophy, etc.helpful for:-
(1) this art of yoga-liberation.
(2) the intuitive grasp of the unity of the Real?
M.: Very little. Some knowledge is needed for yoga and it may be found in books. But practical application is the thing needed, and personal example, personal touch and personal instructions are the most helpful aids. As for the other, a person may laboriously convince himself of the truth to be intuited, i.e., its function and nature, but the actual intuition is akin to feeling and requires practice and personal contact. Mere book learning is not of any great use. After realisation all intellectual loads are useless burdens and are thrown overboard as jetsam. Jettisoning the ego is necessary and natural.
D.: It is said that Divine Grace is necessary to attain successful undistracted mind (samadhi). Is that so?
M.: We are God (Iswara). Iswara Drishti (i.e., seeing ourselves as God) is itself Divine Grace. So we need Divine Grace to get God’s Grace.Maharshi smiles and all devotees laugh together.
