This document discusses the major religious developments in early India, focusing on Buddhism. It examines how religious ideas were compiled in texts and reflected in architecture and sculpture. Key figures discussed include Mahavira, founder of Jainism, and Gautama Buddha, who taught the four noble truths and eightfold path to enlightenment. Buddhism emphasized that the world is transient, soulless, and filled with sorrow, but that following Buddha's teachings can help one rise above worldly troubles. The Buddhist sangha, or monastic community, spread Buddha's teachings.
