Do not look at anybody in terms of friend or foe, brother or cousin; do not fritter away your mental energies in thoughts of friendship or enmity. Seeking the Self everywhere, be amiable and equal-minded towards all, treating all alike.
Just as a stone, a tree, a straw, grain, a mat, a cloth, a pot, and so on, when burned, are reduced to earth (from which they came), so the body and its sense organs, on being burned in the fire of Knowledge, become Knowledge and are absorbed in Brahman, like darkness in the light of the sun.
Each thing tends to move towards its own nature. I always desire happiness which is my true nature. My nature is never a burden to me. Happiness is never a burden to me, whilst sorrow is.
Even after the Truth has been realised, there remains that strong, obstinate impression that one is still an ego - the agent and experiencer. This has to be carefully removed by living in a state of constant identification with the supreme non-dual Self. Full Awakening is the eventual ceasing of all the mental impressions of being an ego.
