In Mahayana, the universe Buddhism is populated with celestial buddhas, bodhisattvas, and deities that assist and inspire the Buddhist practitioner. Among the most popular are Kuan Yin, the Medicine Buddha.
In Buddhism, the purpose of life is to end suffering. The Buddha taught that humans suffer because we continually strive after things that do not give lasting happiness.
The Buddha said of death: Life is a journey. Death is a return to earth. The universe is like an inn. The passing years are like dust. Regard this phantom world As a star at dawn, a bubble in a stream, A flash of lightning in a summer cloud, A flickering lamp - a phantom - and a dream
