All living beings are naturally and instinctively struggling for freedom from sorrow and suffering. So also do they seek pleasure and happiness. The Upaniṣads, the ancient and basic works of Hinduism, call this state ‘amṛtatva,’ the state of immortality and bliss. Mokṣa, mukti, nirvāṇa and kaivalya are some of the more common synonyms of the same.
All the Hindu scriptures are unanimous that
Once this goal of amṛtatva is obtained, there is no return to this life of transmigration. The liberated soul will enjoy eternal bliss.
Details of the path as also the nature of amṛtatva differ from school to school of religious philosophies.
