Buddhism became the first world religion by proving its ability to cross ethnic boundaries and speak importantly to multiple civilizations. It tells us that our destiny and final cause is a condition, nirvana that exceeds all telling but is completely fulfilling. Even though Ancient Bihar is not the birthplace of Buddha, it is closely associated with the rise and development of Buddhism. It was the training ground of Gautama Buddha after he became a wondering ascetic, and it was here in Bodh Gaya that he attained supreme spiritual knowledge. His missionary activity was largely carried in Bihar. Rajgriha and Vaisali were his favourite places of residence or monsoon resorts.
