Saṃsāra (sanskrit: संसार; Telugu: సంసారం) literally meaning “continuous flow”, is the cycle of birth, life, death, rebirth or reincarnation) within Buddhism, Hinduism, Bön, Jainism, Sikhism, and other Indian religions. The word has its origins in the sramanic traditions of ancient India, and is today used in many modern Indian languages to refer to the physical world, or family, or the universe. In modern parlance, samsara refers to a place, set of objects and possessions, but originally, the word referred to a process of continuous pursuit or flow of life. In accordance with the literal meaning, the word should either refer to a continuous stream of consciousness, or the continuous but random drift of passions, desires, emotions, and experiences.
In most Indian religions, life is not considered to begin with birth and end in death, but as a continuous existence in the present lifetime of the organism and extending beyond. The nature of the actions (karma) committed during the course of each lifetime, (good or ill) determines the future destiny of each being. Samsara is closely linked with the idea of rebirth (or reincarnation), but mainly refers to the condition of life, and the experience of life.
In Buddhism, at the moment of death the consciousness (consciousness of the different senses, such as eye consciousness, ear consciousness etc.), acts as the seed for the spawning of the new consciousness in a new biological structure, conducive to the volitional (Saṅkhāras) impulses at the moment of death (which are themselves affected by previous volitional impulses). In other Indian religions, the volitional impulses accrued from the present life are transmitted to a consciousness structure popularly known as the soul, which, after an intermediate period (in Tibetan called the bardo), forms the basis for a new biological structure that will result in rebirth and a new life. This cyclical process ends in the attainment of moksha.
