It was founded in India in the sixth centy BC by a Hindu prince,who was called the Buddha, or ' Enlightened One'. He left his palace and his wife and child because he wanted to think about the problem of human suffering. After six years of studying, he sat down under a tree, and finally he understood the reason for people's unhappiness. According to Buddha, we are unhappy because we are attached to people and things in a world where nothing is permanent. We can find peace of mind by following the right path, and through meditation. Buddha is not a god; he is a guide to truth and self-knowledge.
