Article: Within Buddhism, samsara is defined as the continual repetitive cycle of birth and death that arises from ordinary beings' grasping and fixating on a self and experiences. Specifically, samsara refers to the process of cycling through one rebirth after another within the six realms of existence,[note 2] where each realm can be understood as physical realm or a psychological state characterized by a particular type of suffering. Samsara arises out of avidya (ignorance) and is characterized by dukkha (suffering, anxiety, dissatisfaction). In the Buddhist view, liberation from samsara is possible by following the Buddhist path.
