The bhavacakra (Sanskrit: भवचक्र; Pāli: bhavacakka; Tibetan: སྲིད་པའི་འཁོར་ལོ, Wylie: srid pa'i 'khor lo) is a symbolic representation of saṃsāra (or cyclic existence). It is found on the outside walls of Tibetan Buddhist temples and monasteries in the Indo-Tibetan region, to help non Buddhists understand Buddhist teachings. It is used in Indian Buddhism and Tibetan Buddhism.
