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.
Adi ShankaraDo 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.
Adi ShankaraThe treasure I have found cannot be described in words, the mind cannot conceive of it.
