Samsara

Otto_Ex talks about samsara
Saṃsāra is a Sanskrit word that means "wandering" as well as "world," so it means "running around in circles."
Saṃsāra is referred to with terms or phrases such as transmigration/reincarnation, karmic cycle, and "cycle of aimless drifting, wandering or mundane existence".
When related to the theory of karma it is the cycle of death and rebirth.
