Krishna,Geeta,Chapter 5, Verse 27-28.

Shutting out all external sense objects, keeping the eyes and vision concentrated between the two eyebrows, suspending the inward and outward breaths within the nostrils--thus controlling the mind, senses and intelligence, the transcendentalist becomes free from desire, fear and anger. One who is always in this state is certainly liberated.

Krishna,Geeta,Chapter 5, Verse 29.

The sages, knowing Me as the ultimate purpose of all sacrifices and austerities, the Supreme Lord of all planets and demigods and the benefactor and well-wisher of all living entities, attain peace from the pangs of material miseries.
