Matsya Purana — The Battle at Tripura: Shiva’s Strategy
इलावृतमिति ख्यातं तद्वर्षं विस्तृतायतम् यत्र यज्ञो बलेर्वृत्तो बलिर्यत्र च संयतः //
ilāvṛtamiti khyātaṃ tadvarṣaṃ vistṛtāyatam yatra yajño balervṛtto baliryatra ca saṃyataḥ //
That region is renowned as Ilāvṛta; it is vast and widely extended. There the sacrifice of Bali was performed, and there too Bali was restrained (subdued and bound).
This verse is not about Pralaya; it belongs to the cosmographic mapping of regions (varṣas) and marks Ilāvṛta as a vast central land associated with famous divine events.
By recalling Bali’s yajña and his restraint, the verse indirectly highlights the Purāṇic ethic that royal power and ritual merit must remain under dharma and divine order, not unchecked sovereignty.
The explicit ritual element is yajña: Ilāvṛta is presented as a sanctified landscape remembered for a major sacrifice and its consequence, reinforcing the idea that places gain tīrtha-like prestige through great rites and dharmic events.
