Adhyāya 31: Rājasūya-samāgama — The Gathering of Kings and the Ordering of Hospitality
प्रतिगृह्म च तां सुभ्रूं नीलराज्ञ: सुतां तदा । चक्रे प्रसादं भगवांस्तस्य राज्ञो विभावसु:
pratigṛhya ca tāṁ subhrūṁ nīlarājñaḥ sutāṁ tadā | cakre prasādaṁ bhagavāṁs tasya rājño vibhāvasuḥ ||
Vaiśampāyana said: Having then accepted that fair-browed maiden, the daughter of King Nīla, the blessed Vibhāvasu (Agni) bestowed his gracious favor upon that king.
वैशम्पायन उवाच
The verse highlights dharma expressed as proper hospitality and faithful fulfillment of one’s duty: when a king acts with reverence and gives what is rightly offered at the right time, divine grace (prasāda) follows, reinforcing the moral economy of reciprocity between humans and the sacred.
Vaiśampāyana narrates that Agni (Vibhāvasu), having accepted the beautiful daughter of King Nīla, becomes pleased and grants the king his favor—marking the successful completion of the offering/arrangement and the resulting blessing upon the ruler.
