Saṃsāra in Buddhism and Hinduism is the beginningless cycle of repeated birth, mundane existence and dying again. Samsara is considered to be dukkha, suffering, and in general unsatisfactory and painful, perpetuated by desire and avidya (ignorance), and the resulting karma.

Buddhism, also known as Buddha Dharma and Dharmavinaya, is an Indian religion and philosophical tradition based on teachings attributed to the Buddha. It is the world's fourth-largest religion, with over 520 million followers, known as Buddhists, who comprise seven percent of the global population. Buddhism originated in the eastern Gangetic plain as a śramaṇa–movement in the 5th century BCE, and gradually spread throughout much of Asia via the Silk Road.
