Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
श्रावस्ताद्बृहदश्वो ऽभूत् कुवलाश्वस् ततो ऽभवत् धुन्धुमारत्वमगमद् धुन्धुनाम्ना हतः पुरा //
śrāvastādbṛhadaśvo 'bhūt kuvalāśvas tato 'bhavat dhundhumāratvamagamad dhundhunāmnā hataḥ purā //
From Śrāvasta was born Bṛhadaśva; from him arose Kuvalāśva. He came to be known as Dhundhumāra, for in ancient times he had slain the being named Dhundhu.
This verse does not address pralaya; it records a dynastic succession and explains how Kuvalāśva acquired the epithet Dhundhumāra after killing Dhundhu.
By highlighting a king famed for destroying a harmful being (Dhundhu), the verse reflects the kṣatriya duty of protection—removing threats and maintaining order as part of righteous kingship.
No vastu, temple, or ritual procedure is mentioned in this verse; its focus is genealogical and on the origin of a royal title.
