Buddhism is an Indian religion attributed to the teachings of the Buddha, supposedly born Siddhārtha Gautama, and also known as the Tathāgata (“thus-gone”) and Sakyamuni (“sage of the Sakyas”). Early texts have his personal name as “Gautama” or “Gotama” (Pali) without any mention of “Siddhārtha,” (“Achieved the Goal”) which appears to have been a kind of honorific title when it does appear. The details of Buddha’s life are mentioned in many Early Buddhist Texts but are inconsistent, and his social background and life details are difficult to prove, the precise dates uncertain.
The evidence of the early texts suggests that he was born as Siddhārtha Gautama in Lumbini and grew up in Kapilavasthu, a town in the plains region of the modern Nepal-India border and that he spent his life in what is now modern Bihar and Uttar Pradesh. Some hagiographic legends state that his father was a king named Suddhodana, his mother was Queen Maya, and he was born in Lumbini gardens. However, scholars such as Richard Gombrich consider this a dubious claim because a combination of evidence suggests he was born in the Shakyas community – one that later gave him the title Shakyamuni, and the Shakya community was governed by a small oligarchy or republic-like council where there were no ranks but where seniority mattered instead. Some of the stories about Buddha, his life, his teachings, and claims about the society he grew up in may have been invented and interpolated at a later time into the Buddhist texts.
According to the Buddhist sutras, Gautama was moved by the innate suffering of humanity and its endless repetition due to rebirth. He set out on a quest to end this repeated suffering. Early Buddhist canonical texts and early biographies of Gautama state that Gautama first studied under Vedic teachers, namely Alara Kalama (Sanskrit: Arada Kalama) and Uddaka Ramaputta (Sanskrit: Udraka Ramaputra), learning meditation and ancient philosophies, particularly the concept of “nothingness, emptiness” from the former, and “what is neither seen nor unseen” from the latter.
Finding these teachings to be insufficient to attain his goal, he turned to the practice of asceticism. This too fell short of attaining his goal, and then he turned to the practice of dhyana, meditation. He famously sat in meditation under a Ficus religiosa tree now called the Bodhi Tree in the town of Bodh Gaya in the Gangetic plains region of South Asia. He gained insight into the workings of karma and his former lives, and attained enlightenment, certainty about the Middle Way (Skt. madhyamā-pratipad) as the right path of spiritual practice to end suffering (dukkha) from rebirths in Saṃsāra. As a fully enlightened Buddha (Skt. samyaksaṃbuddha), he attracted followers and founded a Sangha (monastic order). Now, as the Buddha, he spent the rest of his life teaching the Dharma he had discovered and died at the age of 80 in Kushinagar, India.
Buddha’s teachings were propagated by his followers, which in the last centuries of the 1st millennium BCE became over 18 Buddhist sub-schools of thought, each with its own basket of texts containing different interpretations and authentic teachings of the Buddha; these over time evolved into many traditions of which the more well known and widespread in the modern era are Theravada, Mahayana, and Vajrayana Buddhism.
