Bhagavad Gita Chapter 11, Verse 14

ततः स विस्मयाविष्टो हृष्टरोमा धनञ्जयः | प्रणम्य शिरसा देवं कृताञ्जलिरभाषत ||

tataḥ sa vismayāviṣṭo hṛṣṭa-romā dhanañjayaḥ praṇamya śirasā devaṁ kṛtāñjalir abhāṣata

Then Arjuna, overwhelmed with wonder, with hair standing on end, bowing down with his head to the Lord, with folded hands, spoke.

Arjuna's physical and emotional response to the cosmic vision. 'Tataḥ sa vismayāviṣṭo'—then (tataḥ), he (saḥ) overwhelmed with wonder (vismayāviṣṭaḥ). 'Hṛṣṭa-romā dhanañjayaḥ'—with hair standing on end (hṛṣṭa-romā), Arjuna (dhanañjayaḥ). 'Praṇamya śirasā devaṁ'—bowing down (praṇamya) with the head (śirasā) to the Lord (devam). 'Kṛtāñjaliḥ abhāṣata'—with folded hands (kṛtāñjaliḥ), he spoke (abhāṣata). Arjuna is completely overwhelmed—his body responds with hair standing on end, his heart is filled with wonder, and he bows in reverence. This verse shows the natural response to witnessing the cosmic form: overwhelming wonder and deep reverence. The vision is so profound that it elicits a physical and emotional response.
