Sanskrit
ततः स विस्मयाविष्टो हृष्टरोमा धनञ्जयः । प्रणम्य शिरसा देवं कृताञ्जलिरभाषत ॥
tataḥ sa vismayāviṣṭo hṛṣṭaromā dhanañjayaḥ praṇamya śirasā devaṃ kṛtāñjalir abhāṣata
Translation
Then he, Dhananjaya, overwhelmed with astonishment, his hair upstanding, bowed down his head to the Shining One, and with joined palms spake.

Explanation
The same physiology from chapter 1’s collapse resurfaces almost verbatim — hair standing on end (hṛṣṭaromā here, romaharṣa at 1.29) — but the posture around it has flipped. In chapter 1 the trembling body was refusing to fight; here it’s the involuntary response to something too large to process, and instead of dropping his bow he bows his own head. Arjuna is about to speak for the next thirty-one verses almost without interruption — the longest unbroken outpouring given to any character in the entire poem.
