Nālandā - Even a modern visitor to the ruins of Nalanda University cannot fail to appreciate the magnificence of this ancient place of learning. At its pinnacle as many as 10,000 monks lived and studied at this site. The list of its famous students and teachers reads as a who's who of Buddhism's greatest thinkers: Nagarjuna, Aryadeva, Shantideva, Asanga, Vasubandhu, Padmasambhava himself—just to name a few—all studied and/or taught at Nalanda.

Located on the site of a mango grove where Buddha himself often visited, the university's date of origin is not known for certain, although some historians now think it dates to the time of Ashoka in the fourth century BC. What is known is that for at least one thousand years, until its destruction by Mogul invaders around 1200 AD, it was the most important place of learning of the ancient world, not only for Hinayana and Mahayana philosophy but medicine, logic, astrology, and many other subjects as well.
The lecture halls cover many acres of land lined up along a long road that divides the teaching area from the adjoining temples. Along the edge of each lecture hall were rooms for the monks and their teachers. What remains is for the most part no more than several meters high, but the plan of the monasteries is still clearly in evidence.
The great library of Nalanda University was so vast that it is reported to have burned for three months after the Moguls set fire to it, sacked and destroyed the monasteries, and drove the monks from the site. His Holiness the Dalai Lama rarely starts a teaching without mentioning that it is in the "great tradition of Nalanda University".
Located near "Vulture's Peak" (not far from Rajagriha) in Bihar Province of India, it can be reached by a few hours drive from Bodhgaya, the historic pilgrimage site where the Buddha attained enlightenment.
Jetsun Taranatha explains that Nalanda is the place where Shariputra was born and attained arhathood. According to a prophecy saying that the Mahayana will spread greatly if they were taught at the place of Shariputra, and if taught at the place of Maudgalyayana Buddhists were going to be very powerful but the teachings wouldn’t spread that much. Ashoka was the founder of the first monastery in Nalenda.
