What is the final goal of Buddhism?

To overcome non-virtue

The final goal of Buddhism is to reach nirvana through virtuous living and meditation.

The final goal of Buddhism is to reach nirvana through virtuous living and meditation. Nirvana is a state of liberation and enlightenment, where one transcends suffering and the cycle of rebirth. It is achieved by following the Noble Eightfold Path, which includes practices such as ethics, meditation, and wisdom. Buddhism does not aim to move into another caste during reincarnation, achieve a union with Brahman (which is a concept in Hinduism), or specifically overcome non-virtue, although the path to nirvana involves cultivating virtuous qualities and overcoming negative mental states.
