The Upanishads

Jivanmukti - Liberation While Living

Freedom attained while still in the body.

A jivanmukta is one who has realized the Self while still alive. Though the body continues, the sage lives in freedom, untouched by karma, seeing Brahman everywhere.

The wise one, having known Brahman, becomes Brahman even while living.

Traditional, Advaita Teachings

Liberation does not require death of the body.
