Mahayantra (महायन्त्रा, IAST: Mahāyantrā) is a Sanskrit-origin Hindu girl-name meaning “She who is the supreme sacred geometric diagram”. From mahā (great) and yantra (sacred geometric instrument), this name identifies Lalitā with the Śrī Yantra — the supreme diagram that is her very body in geometric form.

Meaning, etymology & significance

A yantra is a sacred diagram that serves as a visual mantra, concentrating divine energy within precise geometric forms. The Śrī Yantra, composed of nine interlocking triangles, is considered the Mahāyantra par excellence, representing the union of Śiva and Śakti and the entire cosmos in miniature. As Mahāyantrā, Lalitā declares that the living universe itself is her sacred diagram — every form a facet of her geometric grace.

This epithet is particularly honored in the Śrīvidyā tradition, where worship of the Śrī Yantra is considered direct worship of the Goddess. Pronounced mah-haa-yun-traa, keeping both long ā sounds deliberate and clear.
