Evolution of love

First

First convince yourself about your true nature as has been expounded so far, and then adopt the regular practice as follows: find a quiet spot, sit quietly, calm and relaxed; check the outward flow of thoughts. With an attitude of renunciation towards all that is manifest, the mind should be turned inwards, away from the sense objects, to the core of the Heart.

Then give up gradually your identification first with the gross physical body and then with the subtle body and the causal body, and let your mind be one with space.
