ततः स विस्मयाविष्टो हृष्टरोमा धनञ्जयः ।
प्रणम्य शिरसा देवं कृताञ्जलिरभाषत ।। ११.१४ ।।

tataḥ sa vismayāviṣṭo hṛṣṭa-romā dhanañ-jayaḥ |
praṇamya śirasā devaṁ kṛtāñjalir-abhāṣata || 11.14 ||

Vyasadeva wants to take the readers and listeners to a refined level of spiritual introspection, when he describes what followed instantly.
