Buddhism is the world's fourth largest religion with over 500 million people followers. Founded in India 600 years before the birth of Christ, Buddhism centres around the teachings of a Prince named Siddhartha Gautama, whom at the age of 35 was reported to have attained Enlightenment after meditating for 49 days straight under the Bodhi tree, thus becoming known as the Buddha (the Awakened One). For several centuries the Buddha's teachings of the Four Noble Truths and Eightfold Path were passed orally through a practice of recitation and memorisation by the Sangha, a group of disciplined monks and nuns. Later Buddhism spread throughout Asia via three primary schools; Theravada, Mahayana, and Vajrayana. Because Buddhists value the timeless importance of the teaching (the dharma), over worshipping gods, many Buddhist meditation practices are taught today in secular and scientific settings.
