jivanmukta

Jivanmukta (from the Sanskrit words jiva and mukti) is a unique concept in Hindu philosophy, and that too, particularly in the school of philosophy known as advaita. The word means 'One who is liberated while alive'. The ultimate goal of Hinduism is Liberation from the cycle of births and deaths. This Liberation is technically called 'moksha'. In all schools of Hindu philosophy except advaita, Liberation is necessarily an event after the death of the body, if at all. But the advaita school of Shankara, envisages that Man is already liberated, his soul is already free, he has only to realise so. So such souls who have had this realisation, are called jivanmuktas, though they are extremely rare.
