Nalanda and Vikramashila

For more than seven centuries, from roughly the fifth to the twelfth century CE, Nalanda Mahavihara stood as the philosophical capital of the Buddhist world. At its height it drew more than ten thousand monks and scholar-pilgrims from Tibet, China, Korea, Japan, and Sri Lanka, supported across generations by royal patrons including the Gupta emperors and King Harshavardhana. A few centuries later and further east in Bihar, Vikramashila rose as its counterpart, founded by the Pala emperor Dharmapala in the eighth century and devoted especially to the study of Tantric Buddhism. Together the two mahaviharas shaped how Buddhist philosophy, logic, and practice were taught across Asia for half a millennium.

At Nalanda, inner realization was never taken on faith alone. Monks tested their understanding daily through formal debate and the rigorous study of Madhyamaka (the middle-way philosophy of emptiness), Yogachara (the mind-only school of Buddhist thought), and Abhidharma (systematic analysis of mind and phenomena) treatises. The curriculum also reached well beyond religious study, into Buddhist logic, grammar, medicine, and mathematics, covering the full range of classical learning. Tradition holds that admission itself was a trial: a gatekeeper scholar, the dvarapandita, questioned each aspiring student at the threshold, and only a small fraction who presented themselves were judged ready to enter. The campus held monasteries, lecture halls, and the Dharmaganja, a complex of three multi-story library buildings: Ratnasagara, Ratnodadhi, and Ratnaranjaka. The tallest, Ratnodadhi, is said in Tibetan sources to have risen nine stories and held the rarest of the collection's manuscripts.

The campus's most monumental structure, the Great Stupa built over relics of Sariputra, the Buddha's foremost disciple in wisdom, grew in stages from the third century BCE to the sixth century CE, each ruling dynasty adding its own tier. Sariputra himself was born and is said to have passed into Parinirvana in the nearby village of Nalaka, giving the site its own claim on his memory long before the mahavihara was built around it. The Chinese pilgrim Xuanzang studied at Nalanda for five years in the seventh century and left the most detailed surviving account of its daily life, and a memorial hall on the grounds today honors him as the Master of the Law who carried its teachings home to China.

The philosophy developed at Nalanda and Vikramashila reshaped Buddhist thought across Asia. Acharya Nagarjuna, earlier than either institution's founding but foundational to the tradition both carried forward, established the philosophy of emptiness, shunyata, and the middle way, madhyamaka, that their scholars continued to refine for centuries. Acharya Shantideva, a monk of Nalanda, composed the Bodhicaryavatara, the Way of the Bodhisattva, one of Mahayana Buddhism's most beloved texts on compassion and the bodhisattva path. Acharya Atisha Dipankara, who studied and later held high office at Vikramashila, carried its lineages of philosophy and tantra across the Himalayas to Tibet in the eleventh century, a journey that reshaped Tibetan Buddhism at its foundations.

Among the verses composed at Nalanda, Shantideva's closing vow in the Bodhicaryavatara remains among the most recited in Mahayana practice today:

Vikramashila was laid out with its own deliberate symbolism: a central temple holding a life-size image of the Mahabodhi Buddha, surrounded by 108 shrines. A perimeter wall was pierced by six gates, each guarded not by soldiers but by a resident scholar whose task was to examine and admit visiting debaters. Tradition names the six gatekeeper-pandits of the monastery's height in the tenth century, and among them stood Naropa, later revered across Tibetan Buddhism as the teacher of Marpa in the lineage that produced Milarepa. Atisha Dipankara himself rose to become a senior abbot at Vikramashila before his journey to Tibet, carrying out of its six gates a body of philosophy and tantric practice that Vikramashila had spent two centuries refining.

Nalanda's centuries as a living center of learning ended in the final years of the twelfth century, when an invading army set fire to its library and scattered its community; tradition holds the manuscripts burned for months. Yet the teaching did not end with the buildings. In the years before and after this loss, monks and scholars connected to Nalanda and Vikramashila had already carried texts, lineages, and students across the Himalayas into Tibet, where Atisha's reforms and the manuscripts preserved there kept the mahaviharas' learning alive long after the campuses themselves fell silent. The excavated ruins of Nalanda, rediscovered and studied since the nineteenth century, were inscribed as a UNESCO World Heritage Site in 2016, and pilgrims and scholars continue to walk its grounds today.
