What is the term that indicates a state of ultimate peace and liberation in Buddhism?

The term that indicates a state of ultimate peace and liberation in Buddhism is Nirvana. In Buddhist philosophy, Nirvana represents the end of suffering, the cessation of the cycle of birth, death, and rebirth (samsara), and the realization of enlightenment. It is considered the ultimate goal of Buddhist practice, symbolizing the liberation from desires and attachments that lead to suffering.

Achieving Nirvana means that an individual has transcended the limitations of the self and experienced a profound state of bliss and tranquility. This concept is essential to understanding Buddhist teachings, as it emphasizes the importance of letting go of attachments and desires to attain a higher state of consciousness and peace.

The other terms listed have different meanings and are associated with other religious or philosophical traditions. For example, Zen relates to a school of Mahayana Buddhism that emphasizes meditation, while Moksha is a term from Hinduism that signifies liberation from the cycle of rebirth and union with the divine. Samadhi refers to a state of meditative consciousness found in various spiritual practices, but it is not synonymous with the ultimate liberation described by Nirvana in Buddhism.
