cycle of birth and death; circle of reincarnation
Buddhist term referring to the endless cycle of birth, death, and rebirth (samsara).
The concept of the cycle of birth and death is one of the central teachings of Buddhism.
輪廻 alone means 'transmigration of souls' or 'reincarnation'; 輪廻生死 explicitly emphasizes the cycle of birth and death.
生死 alone means 'life and death'; in Buddhist context it often refers to the cycle of birth and death, but 輪廻生死 is a more formal compound.
Compound of 輪廻 (りんね, 'reincarnation') and 生死 (しょうじ, 'birth and death'), both Buddhist terms. The exact historical derivation is uncertain, but the combination is a standard Buddhist expression.
