Teachings of Vivekachudamani of Adi Shankaracharya

The resting of the mind steadfastly on its Goal (viz. Brahman) after having detached itself from manifold sense-objects by continually observing their defects, is called Shama or calmness. (Verse 22)

The dull-witted man thinks he is only the body; the book-learned man identifies himself with the mixture of body and soul. But the sage, possessed of realization through discrimination, looks upon the eternal Atman as his Self and thinks, “I am Brahman (the Self of all)”. (Verse 160)

Clouds are brought in by the wind and again driven away by the same agency. Similarly, man’s bondage is caused by the mind, and Liberation too is caused by that alone. (Verse 172)
