Bhavacakra

The bhavacakra (Sanskrit; Pāli: bhavacakka; Tibetan: srid pa'i 'khor lo) is a symbolic representation of saṃsāra (or cyclic existence) found on the outside walls of Tibetan Buddhist temples and monasteries in the Indo-Tibetan region. In the Mahayana Buddhism, it is believed that the drawing was designed by the Buddha himself in order to help ordinary people understand Buddhist teachings.
