Buddhism – a dharmic religion and philosophy based on the teachings of the Buddha, Siddhārtha Gautama. The basic teachings of Buddhism have to do with the nature of suffering or dissatisfaction (dukkha) and its avoidance through ethical principles (the Eightfold Path). Buddhism originated in India, and is today largely followed in East Asia, including China, Japan, Korea, Tibet, and Thailand. Buddhism is divided into different sects and movements, of which the largest are the Mahayana, Theravada, and Vajrayana.
