Boudh Gaya

Bihar has been the ultimate pilgrimage for the Buddhists. It was in Bodh Gaya (Bihar) where Lord Buddha became enlightened. The prime Buddhist pilgrimages/sites of Bihar include Vaishali (where Lord Buddha preached many a times and announced his impending nirvana), Bodhgaya, where Buddha attained enlightenment (nirvana) and Nalanda, which developed as a great center of Buddhist learning. Rajgir is yet another important Buddhist pilgrimage site in Bihar, where Lord Buddha spent much time giving sermons.
