In Hinduism, mukti is liberation from worldly bondages and suffering. As per Hindu philosophy, birth is considered as bondage (Bhagavad Gita II.51). Therefore, when one is liberated from the endless cycle of births and rebirths, a person attains mukti.
According to Advaita Vedanta, liberation is of two types – jivanmukti and vedehamukti. Avidya (nescience or delimited knowledge) is the root cause of the world. Liberation is to become free from the clutches of avidya. Jivanmukta is emancipation during one’s lifetime. Videhamukti is deliverance through a release from the body.
In Vasihnava philosophy, mukti is four kinds – salokya, samipya, sarupya and sayujya. When a sadhaka (aspirant) dwells in the same world as God, it is called salokya. Samipya means staying close to God. In sarupya mukti, the aspirant acquires equality in power and all the divine attributes of God (Chandogya Upanishad II.20.2). Ultimately, one attains intimate union with God, the sayujya kind of liberation.
