Nalanda mahavihara

Nalanda (IAST: Nālandā, pronounced [naːlən̪d̪aː]) was a renowned Buddhist mahavihara (great monastery) in medieval Magadha (modern-day Bihar), eastern India. Widely considered to be among the greatest centres of learning in the ancient world and often referred to as "the world's first residential university", it was located near the city of Rajagriha (now Rajgir), roughly 90 kilometres (56 mi) southeast of Pataliputra (now Patna). Operating for almost a thousand years from 427 CE until around 1400 CE, Nalanda mahavihara played a vital role in promoting the patronage of arts, culture and academics during the 5th and 6th century CE, a period that has since been described as the "Golden Age of India" by scholars. The characterisation of Nalanda as a "university" in the modern sense has been challenged by scholars. They argue that while it was undoubtedly a major centre of learning, comparing it directly to a modern university is historically imprecise.

Nalanda was established by emperor Kumaragupta I of the Gupta Empire around 427 CE, and was supported by numerous Indian and Javanese patrons – both Buddhists and non-Buddhists. Nalanda continued to thrive with the support of the rulers of the Pushyabhuti dynasty (r. 500–647 CE) and the Pala Empire (r. 750–1161 CE). After the fall of the Palas, the monks of Nalanda were patronised by the Pithipatis of Magadha. Nalanda was attacked by Huns under Mihirakula in the 5th century and again sustained severe damage from an invasion by the Gauda king of Bengal in the 8th Century. During the final invasion it was burnt down by Muhammad Bakhtiyar Khilji (c. 1200), but it managed to remain operational for decades (or possibly even centuries) following his raids.

Over some 750 years, Nalanda's faculty included some of the most revered scholars of Mahayana Buddhism. The historian William Dalrymple said of Nalanda that "at its apex, it was the undisputed scholarly centre of the Mahayana Buddhist world". The faculty and students associated with the monastery included Dharmapala, Nagarjuna, Dharmakirti, Asanga, Vasubandhu, Chandrakirti, Xuanzang, Śīlabhadra, Vajrabodhi, and Dharmasvamin. The curriculum of Nalanda included major Buddhist philosophies like Madhyamaka, Yogachara and Sarvastivada, as well as subjects like the Vedas, grammar, medicine, logic, mathematics, astronomy and alchemy. The mahavihara had a renowned library that was a key source for the Sanskrit texts that were transmitted to East Asia by pilgrims like Xuanzang and Yijing. Many texts composed at Nalanda played an important role in the development of Mahayana and Vajrayana. They include the works of Dharmakirti, the Sanskrit text Bodhisattvacaryāvatāra of Shantideva, and the Mahavairocana Tantra.

The ancient site of Nalanda is a UNESCO World Heritage Site. In 2010, the Government of India passed a resolution to revive the ancient university, and a contemporary institute, Nālandā University, was established at Rajgir. It has been listed as an Institute of National Importance by the Government of India.

Nalanda is about 16 kilometres (10 mi) north of the city of Rajgir and about 90 kilometres (56 mi) southeast of Patna, connected via NH 31, 20 and 120 to India's highway network. It is about 80 kilometres (50 mi) northeast of Bodh Gaya – another important Buddhist site in Bihar. The Nalanda archaeological site is spread over a large area to the northwest of Bargaon (Nalanda) village, and is between the historical manmade lakes Gidhi, Panashokar and Indrapuskarani. On the south bank of the Indrapushkarani lake is the Nava Nalanda Mahavihara – a university founded in its memory. Similarly on the south west bank of the Indrapushkarani lake is Nalanda Open University, the state university named after the ancient Nalanda University.

Mahavihara (Mahāvihāra) is the Sanskrit and Pali term for a great vihāra (centre of learning or Buddhist monastery) and is used to describe a monastic complex of viharas.

According to the early 7th-century Tang dynasty Chinese pilgrim, Xuanzang, the local tradition explains that the name Nālandā (Hindi/Magahi: नालन्दा) came from a nāga (serpent deity in Indian religions) whose name was Nalanda. He offers an alternate meaning "charity without intermission", from "na-alam-da"; however, this split does not mean this. Hiranand Sastri, an archaeologist who headed the excavation of the ruins, attributes the name to the abundance of nālas (lotus-stalks) in the area and believes that Nalanda would then represent the giver of lotus-stalks.

In some Tibetan sources, including the 17th-century work of Taranatha, Nalanda is referred to as Nalendra, and is likely synonymous with Nala, Nalaka, Nalakagrama found in Tibetan literature.
