ततः स विस्मयाविष्टो हृष्टरोमा धनञ्जयः। प्रणम्य शिरसा देवं कृताञ्जलिरभाषत ॥

tataḥ sa vismayāviṣhṭo hṛiṣhṭa-romā dhanañjayaḥ praṇamya śhirasā devaṁ kṛitāñjalir abhāṣhata

Then he, Dhananjaya, overwhelmed with astonishment, his hair upstanding, bowed down his head to the Shining One, and with joined palms spake.

In plain words: Arjuna (Dhananjaya) was filled with amazement, and his hair stood on end. He bowed his head to Krishna, pressed his palms together in respect, and began to speak.
