Νιρβάνα (Enlightenment) is a key concept in Buddhism that represents the ultimate state of liberation from suffering and the cycle of birth and rebirth, known as samsara. It is achieved through the realization of the true nature of reality, leading to the cessation of desires and attachments. In Hinduism, a similar concept exists, often referred to as moksha, which also signifies liberation from the cycle of life and death. Both paths emphasize self-realization, meditation, and ethical living as means to attain this profound state of peace and understanding.
