Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
तथेत्युक्तास्ततस्ते तु जग्मुर् वैवस्वतात्मजाः इक्ष्वाकोश्चाश्वमेधेन चेलः किम्पुरुषो ऽभवत् //
tathetyuktāstataste tu jagmur vaivasvatātmajāḥ ikṣvākoścāśvamedhena celaḥ kimpuruṣo 'bhavat //
Having said, “So be it,” the sons of Vaivasvata (Manu) then departed. And Ikṣvāku, by performing the Aśvamedha sacrifice, became (renowned as) Cela, the Kiṃpuruṣa.
This verse does not describe Pralaya directly; it continues the post-Deluge genealogical stream by noting the movements of Vaivasvata Manu’s sons and Ikṣvāku’s rise through ritual merit.
It highlights royal dharma through the Aśvamedha: the king gains legitimacy and fame by performing Vedic state-rituals, implying that righteous rule is supported by sanctioned yajña and adherence to tradition.
The ritual significance is explicit: the Aśvamedha sacrifice is presented as a transformative, status-conferring rite associated with sovereignty and dynastic establishment.
