The Knowledge Avatāra
Hayagrīva (Sanskrit: haya = horse, grīva = neck/throat — horse-necked) is a distinctive avatāra form of Viṣṇu with a human body and the head of a white horse. He is worshipped as the deity of jñāna (knowledge), śabda (divine speech), and vidyā (learning).
The Myth of Hayagrīva
According to the Purāṇas, when Viṣṇu's head was accidentally severed (by a bow-string) during a period of rest, the gods replaced it with a horse's head. In this form, Viṣṇu slew the demons Madhu and Kaiṭabha who had stolen the Vedas, recovering the sacred knowledge and restoring it to the world.
Worship of Hayagrīva
Hayagrīva is especially worshipped:
- By students before examinations and learning
- At the beginning of scriptural study (svādhyāya ārambha)
- On Śrāvaṇa Pūrṇimā (the full moon of Śrāvaṇa — the day associated with Vedic learning)
Vedānta Deśika was an ardent devotee of Hayagrīva and composed the famous Hayagrīva Stotram — a devotional hymn that is recited before the study of any śāstra. The Hayagrīva icon in the Deśika maṭhas is particularly revered.
