Buddhism is the fourth largest religion in the world, being exceeded in numbers only by Christianity, Islam and Hinduism. It was founded in Northern India by the Buddha, Siddhartha Gautama. He was born circa 563 BCE in Lumbini which is in modern-day Nepal. At the age of 29, he left his wife, children and political involvements in order to seek truth. It was an accepted practice at the time for some men to leave their family and lead the life of an ascetic. He studied Brahmanism, but ultimately rejected it. In 535 BCE, he attained enlightenment and assumed the title Buddha (one who has awakened). Buddha's Past - Buddha's original name was Siddhartha. It meant one who had accomplished his aim.
