The document discusses the Buddhist Wheel of Life symbol. It represents samsara, the cycle of life, death and rebirth. The Wheel of Life is believed to have been designed by Buddha himself to help people understand Buddhist teachings about impermanence, suffering and lack of self. It depicts the six realms of existence - heavenly, demi-god, human, animal, hungry ghost and hell realms - and how beings cycle through them based on karma. The Wheel of Life acts as a mirror to remind people of aging, sickness and death.
