Mohatamisraghna (मोहतमिस्रघ्न, IAST: Mohatamisraghna) is a Sanskrit-origin Hindu boy-name meaning “Destroyer of the darkness born of delusion”. Compounded from moha (delusion, spiritual bewilderment), tamisra (thick darkness), and ghna (slayer, destroyer), this name reveals Vishnu as the one who annihilates the dense inner darkness that arises when the soul mistakes illusion for reality.

Meaning, etymology & significance

Moha is the primal forgetting — the soul's confusion about its own divine nature — and tamisra is the darkest of the Puranic hells as well as a metaphor for the most impenetrable ignorance. By combining both, the epithet intensifies the imagery: Vishnu does not merely dispel ordinary ignorance but eradicates even its deepest, most suffocating manifestation. The suffix ghna, cognate with han (to strike), has been used throughout Vedic literature to honor deities as vanquishers of specific forces, and its use here places Vishnu in direct opposition to the root cause of all suffering.

This epithet is borne by Vishnu in His capacity as jñāna-dīpa, the lamp of wisdom, and is particularly beloved in Vaishnava philosophy which sees liberation as the dissolution of moha through devotion and knowledge. Pronounced mo-ha-ta-mis-ra-ghna, it can be shortened to Tamisraghna for practical use as a given name.
