A jivanmukta has reached perfection in four different ways: absolute freedom from egoism, doubt, fear and grief.
A jivanmukta is also considered a full-fledged yogi. He/she does not care for the wants of the body. He/she is not afraid of death, nor does he/she have a longing to live. For him/her, prayers do not exist, nor mantras, submission or devotion. Nothing exists for a jivanmukta other than the total knowledge of the true Self.
Yoga is a known technique for acquiring the qualities necessary to become a jivanmukta and the state of jivanmukti is the ultimate goal of yoga.
