Trikonantaradipika (त्रिकोणान्तरदीपिका, IAST: Trikoṇāntaradīpikā) is a Sanskrit-origin Hindu girl-name meaning “She who is the lamp blazing within the triangle”. Trikoṇa (triangle, the primary yantra form), antara (within, interior), and dīpikā (small lamp, illuminatrix) together identify Lalitā as the luminous point of pure consciousness glowing at the center of the Śrī Yantra's innermost triangle.

Meaning, etymology & significance

The Śrī Yantra's innermost bindu is enclosed by the primary trikoṇa, and Lalitā as trikoṇāntaradīpikā is that self-luminous point — the lamp that illuminates from within, requiring no external source of light. The image captures the nondual teaching that she is both the container and the contained, both the form and the formless awareness shining through it.

This is a richly tantric epithet of Śrī Lalitā, beloved in Śrī Vidyā upāsanā. Pronounced tri-ko-ṇān-ta-ra-dī-pi-kā, its length makes it more suited to liturgical use, though Dipika extracted from it is a widely used girl's name.
