The bhavacakra is a symbolic representation of samsara (or cyclic existence) found on the outside walls of Tibetan Buddhist temples and monasteries in the Indo-Tibetan region. In the Mahayana Buddhist tradition, it is believed that the drawing was designed by the Buddha himself in order to help ordinary people understand the Buddhist teachings.
The bhavacakra is popularly referred to as the wheel of life. This term is also translated as wheel of cyclic existence or wheel of becoming.
