What is the difference between Hinduism and Nirvana

Answers

Answer:

The most ancient texts of Hinduism such as the Vedas and early Upanishads don't mention the soteriological term Nirvana. This term is found in texts such as the Bhagavad Gita and the Nirvana Upanishad, likely composed in the post-Buddha era. The concept of Nirvana is described differently in Buddhist and Hindu literature. Hinduism has the concept of Atman – the soul, self asserted to exist in every living being, while Buddhism asserts through its anatman doctrine that there is no Atman in any being. Nirvana in Buddhism is "stilling mind, cessation of desires, and action" unto emptiness, states Jeaneane Fowler, while nirvana in post-Buddhist Hindu texts is also "stilling mind but not inaction" and "not emptiness", rather it is the knowledge of true Self (Atman) and the acceptance of its universality and unity with metaphysical Brahman.
