You never identify yourself with the shadows cast by your body, or with its reflection, or with the body you see in a dream or in your imagination. Therefore you should not identify yourself with this living body either.
Adi ShankaraEven 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 be proud of wealth, people, relations and friends, or youth. All these are snatched by time in the blink of an eye. Giving up this illusory world, know and attain the Supreme.
Adi ShankaraWhat is enquiry into the Truth? It is the firm conviction that the Self is real, and all, other than That, is unreal.
Adi ShankaraJust 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.
