Bhavachakra

The bhavachakra or wheel of life is a visual teaching aid and meditation tool symbolically representing saṃsāra. It is found on the walls of Tibetan Buddhist temples and monasteries in the Indo-Tibetan region, to help both Buddhists understand the core Buddhist teachings. The image consists of four concentric circles, held by Yama, the lord of Death, with an image of the Buddha pointing to the moon metaphorically representing the possibility for liberation from the suffering of reincarnation.
