Vedanta lays all the emphasis upon mental culture. It says ‘Begin your Sadhana from the mental plane’ and psychology is the science that has hold upon the mental plane. Vedanta is a complete Divine Psychology. We have forgotten our real nature. What is the remedy for this? To remember it and to reassert it. This is one point of Sadhana—auto-suggestion is the mainstay, the pillar of Vedanta.
