Question

What factors were responsible for the popularity of buddhism?

Answer 1

Buddhism also became popular in India as it meshed with the existing religious traditions known as Jainism, and forms of Hinduism. Jainism and Hinduism were well-established in India from early on. Buddhism shared some notable principles with those ancient traditions, for instance the insistence on non-violence, known as ahimsa, particularly important in Jainism, and the inter-related concepts of nirvana(literally meaning extinction) and moksha(liberation of the soul). These latter two concepts also are fundamental to the much younger Indian religion of Sikhism.
