Nalanda had been an ancient seat of learning and a religious centre that imparted manifold knowledge. It existed in ancient Magadha (presently, Bihar and parts of Bengal, Orisha in India) between the fifth century AD to twelve century AD. It was believed that the term ‘Nalanda’ might have been originated from the word nalam (lotus), or da Nalanda, signifying “giver of knowledge”. The ancient Mahavihara at Nalanda was established during the reign of a king called Śakrāditya, of the Gupta Dynasty. Nalanda was visited by both Buddha and Mahavira around the fifth and sixth centuries BC. It was also the place of birth and nirvana of Sariputta, one of the famous disciples of Buddha. Many of the famous Buddhist scholars had studied and taught at Nalanda including Nagarjuna, who formalized the concept of Sunyata; Dharmapala, the teacher of Xuan Zang; Dharmakirti, the logician; Dinnaga, the founder of Buddhist Logic; Jinamitra Santaraksita, who founded the first monastic order in Tibet; Padmasambhava, the master of Tantric Buddhism; Candrakīrti, Śīlabhadra and Atisa. Nalanda was one of the world's first residential universities.
