Buddhism: Buddhism is a religion indigenous to the Indian subcontinent that encompasses a variety of traditions, beliefs, and practices largely based on teachings attributed to Siddhartha Gautama, who is commonly known as the Buddha (meaning "the awakened one" in Sanskrit and Pāli). The Buddha lived and taught in the eastern part of the Indian subcontinent some time between the 6th and 4th centuries BCE. He is recognized by Buddhists as an awakened or enlightened teacher who shared his insights to help sentient beings end suffering (dukkha) through eliminating ignorance (avidyā) by way of understanding and seeing dependent origination (pratītyasamutpāda) and eliminating craving (taṇhā), and thus attain the highest happiness, nirvāņa (nirvana).

Two major branches of Buddhism are recognized: Theravada ("The School of the Elders") and Mahayana ("The Great Vehicle"). Theravada has a widespread following in Sri Lanka and Southeast Asia. Mahayana is found throughout East Asia and includes the traditions of Pure Land, Zen, Nichiren Buddhism, Tibetan Buddhism, Shingon, and Tiantai (Tendai). In some classifications, Vajrayana—practiced mainly in Tibet and Mongolia, and adjacent parts of China and Russia—is recognized as a third branch, while others classify it as a part of Mahayana. There are other categorisations of these three Vehicles or Yanas.
