The six Buddhist universities of ancient India-
1. Nalanda (500 CE to c. 1200 CE)
Nalanda flourished under the patronage of the Gupta Empire as well as emperors like Harshavardhan and later, the rulers of the Pala Empire. At its peak, the school attracted scholars and students from as far away as Tibet, China, Korea, and Central Asia. It was very likely ransacked and destroyed by Bakhtiyar Khilji in c. 1200 CE.
We get a comprehensive account of Nalanda university from Hieun Tsang, the brilliant Chinese scholar, who came there for his studies during the reign of King Harsha-Siladitya. I – Tsing (675-685) was another Chinese monk who came to India and studied at Nalanda
At the time of Fa-Hian visit it was an ordinary Buddhist monastery. Lama Taranata the Tibetan historian also gives an account of Nalanda in his works. It appears that King Kumara Gupta (AC 415-455) built the first monastery at Nalanda. It was a seminary for training Buddhist monks. Admission to Nalanda was by oral examination. This was done by a professor at the entrance hall. He was called Dvara Pandita. Proficiency in Sanskrit was necessary, as it was the medium of instruction. Casts, creed and nationality were no barriers in keeping with the Buddhist spirit. Nalanda was maintained by the revenue from seven villages which were granted by the king. The study of Mahayana was compulsory for Buddhists. One could also study secular subjects like science, medicine, astrology, fine-arts, literature etc. The six systems of Hindu philosophy were also taught. One could study Hinayana forms of Buddhism.
Nalanda university occupied an area of 30 acres. There were three large libraries bearing the names Ratna-Sagara, Ratna-Nidi and Ratna-Ranjana.
