Tattvamayi (तत्त्वमयी, IAST: Tattvamayyī) is a Sanskrit-origin Hindu girl-name meaning “She who is entirely composed of ultimate truth”. From 'tattva' (truth, reality, principle) and the suffix 'mayī' (filled with, consisting of), this name reveals the Goddess as one whose very being is the living substance of cosmic truth.

Meaning, etymology & significance

The suffix 'mayī' in Sanskrit denotes complete identification — not merely possession of a quality but being entirely constituted by it. Tattvamayyī therefore means the Goddess is not merely the knower of truth but truth itself in its totality. This reflects the Advaitic understanding that the Divine Śakti is identical with ultimate reality (brahman).

Tattvamayyī appears in the Lalitā Sahasranāma as an expression of the Goddess's non-dual identity with the fabric of existence. The name can be adapted to the more flowing form 'Tattvamayī' for personal use; pronounced 'tat-tva-ma-YEE'.
