Grammatical Analysis
Mahāvihāra: [m.] The Great Monastery. Formed by mahā (great, large) + vihāra (monastery).
Orthodox Definition
The Mahāvihāra is the absolute epicenter of orthodox Theravāda Buddhism. Founded in the 3rd century BCE by King Devānampiya Tissa in Anuradhapura, Sri Lanka, it was the headquarters of Venerable Mahinda, the son of Emperor Ashoka who brought Buddhism to the island.
The monks of the Mahāvihāra—the Mahāvihāravāsins—are responsible for preserving the Pali Tipiṭaka in its purest form. They fiercely defended the orthodox Vibhajjavāda doctrine against emerging Mahāyāna and esoteric influences. In the 5th century CE, the great commentator Buddhaghosa traveled explicitly to the Mahāvihāra to translate their ancient Sinhalese commentaries into the Pali Aṭṭhakathā, securing the doctrinal framework that defines global Theravāda today.
When modern practitioners refer to “orthodox Theravāda,” they are explicitly referring to the unadulterated doctrinal positions preserved by the Mahāvihāra lineage.
