Buddhism originated in India in the 6th century BCE and is based on the teachings of Siddhartha Gautama, known as the Buddha. The Buddha attained enlightenment under a Bodhi tree and dedicated his life to teaching others how to reach spiritual enlightenment and escape suffering. Buddhism teaches that life involves suffering and the cycle of rebirth, but followers can reach nirvana through meditation, good deeds, and following the teachings of the Four Noble Truths and Middle Way. Buddhism eventually spread from India to many parts of Asia.
