Nirvana is a key concept in Buddhism that represents the ultimate state of liberation and freedom from suffering. It is often described as the cessation of desire, attachment, and ignorance, leading to a profound sense of peace and enlightenment. Achieving nirvana means breaking free from the cycle of samsara, which is the continuous cycle of birth, death, and rebirth. In Hinduism, nirvana is similarly viewed as a state of spiritual liberation, often associated with the realization of one's true self and unity with the divine. It signifies the end of the soul's journey through various lifetimes and the attainment of eternal bliss. Both traditions emphasize the importance of ethical living, meditation, and self-awareness in reaching this transcendent state.
