In Buddhism, the Wheel of Life is a symbolic representation of samsara, the continuous cycle of birth, life, death. One is liberated from this endless cycle of rebirth when Enlightenment is achieved, and with this goal, the Awakened individual has won Nirvana, the highest state of bliss introduced by Gautama Buddha.
The following diagram illustrates the basic wheel of life. More elaborate versions of this motif have been included in much of the art of these faiths.
