Mahaguhya (महागुह्य, IAST: Mahāguhya) is a Sanskrit-origin Hindu boy-name meaning “The supremely profound and hidden mystery”. From mahā (great) and guhya (secret, hidden, mysterious), derived from the root guh (to conceal), this name reveals Viṣṇu as the ultimate mystery—the most sacred secret that cannot be grasped by ordinary intellect, known only through grace and devotion.

Meaning, etymology & significance

The word guhya comes from the root guh, 'to hide or conceal,' and in Vedic literature it refers to the innermost, most guarded teachings transmitted only from guru to worthy disciple. The Bhagavad Gītā (18.63–64) uses this very word when Kṛṣṇa calls His final teaching 'guhyatamam,' the most secret of all; Mahāguhya therefore points to Viṣṇu as that which is the very essence of all esoteric wisdom. This name is especially treasured in Tantric and Pāñcarātra traditions, where the Lord's innermost nature is said to dwell in the heart-cave (guhā) of every being.

As an epithet, Mahāguhya is found in the Viṣṇu Sahasranāma and in various Upaniṣadic passages describing Brahman as residing in the guhā of the heart; as a personal name it is rare but carries a beautiful mystical resonance. Pronunciation: ma-hā-gu-hya, with the aspirate guhya spoken softly.
