Saṃsāra refers to the continuous cycle of birth, death, and rebirth in Buddhist philosophy, where sentient beings undergo various experiences in different realms of existence. This concept highlights the transient nature of life and emphasizes the importance of understanding one's actions (karma) and their consequences. Saṃsāra is a fundamental aspect of the human experience, teaching that liberation from this cycle is attainable through the development of wisdom, particularly through right view and right intention.
