Buddhism is a religion based on the teachings of Siddhartha Gautama, known as the Buddha, who lived around 2500 years ago in Nepal and India. The key principles of Buddhism are the Four Noble Truths about suffering and its causes and end, and the Eightfold Path to end suffering. Buddhism is split into two main branches, Theravada (Hinayana) and Mahayana. Buddhist literature includes sutras containing the Buddha's teachings, while education focuses on the Four Noble Truths, Eightfold Path, and Buddhist doctrines of suffering, no-self, karma, and enlightenment. Buddhism declined over time as the sangha became morally degraded and Brahmanical religion
