Illustration of the Buddhist death god Yama holding the Bhavacakra, or wheel of life. At the centre are the three poisons; greed (rooster), ignorance (pig) and hatred (snake). They are surrounded by a ring representing karma. Outside this are the six realms of cyclic existence that a being can be rebirthed into. The rim of the wheel is divided into the twelve links of dependent origination, which show the cause and effects of suffering.
