Jainism and Buddhism emerged in India during the 6th century BCE as responses to the ritualistic practices of Brahmanism, focusing on self-discipline, ethics, and equality. Both religions emphasized key teachings such as the importance of non-violence (Ahimsa) and the belief in karma and rebirth, yet they differed significantly in their paths to salvation and philosophical tenets. The chapters detail the causes of these religions' rise, their core teachings, similarities, differences, and the historical context of their spread and decline.
