Living a life of balance in harmony with the world is central to Asian philosophy, as is right behaviour to ensure eventual spiritual liberation. The Wheel of Life or Existence illustrates how right behaviour can influence rebirth. It depicts the Buddhist teachings on suffering, the nature of samsara or cyclic existence and the doctrine of karma or cause and effect. In the centre of the wheel are three animals; a pig, a cockerel and a snake, respectively symbolising the three poisons of ignorance, desire and hatred. Until these poisons are eradicated, they give rise to a meaningless cycle of death and rebirth into any of the six realms of cyclic existence.
