The Wheel of Life
"The Bhavachakra (the Wheel of Life or the Wheel of Becoming) portrays the Buddhist view of samsara. Yama, the fierce Lord of Death, holds the wheel firmly in his grasp. At the center a pig, cock, and snake--symbols of confusion, greed, and hatred--chase each other endlessly, binding beings to the cycle of suffering through the power of karma.
The main section of the wheel shows the six realms of existence: gods, titans, and humans in the upper part, and animals, hungry ghosts, and hell beings below." -back description
