What was the contribution of Buddhism to Indian culture?

The spread of Buddhism enriched Indian culture in the following ways:

1. The teachings of Buddha have been compiled into three books called Tripitakas (three baskets). Another contribution to literature are the tales from the Jataka, which describe the previous births of the Buddha.
2. Many educational centres such as Nalanda, Valabhi and Vikramashila were famous for Buddhist learning.
3. Many beautiful stupas at Sanchi, Valabhi and Nalanda were built.
4. Gandhara sculptures and paintings at Ellora and Ajanta are great examples of Buddhist art.
5. The Buddhists built structures called chaityas (prayer halls), stupas and viharas (monasteries).
