Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
पृषध्रो गोवधाच्छूद्रो गुरुशापादजायत इक्ष्वाकुवंशं वक्ष्यामि शृणुध्वमृषिसत्तमाः //
pṛṣadhro govadhācchūdro guruśāpādajāyata ikṣvākuvaṃśaṃ vakṣyāmi śṛṇudhvamṛṣisattamāḥ //
Pṛṣadhra, because he slew a cow, became a Śūdra through his teacher’s curse. Now I shall recount the lineage of Ikṣvāku—listen, O best of sages.
This verse does not discuss Pralaya; it shifts the narrative into royal genealogy, highlighting karmic causality (sin and curse) as a governing moral principle in history.
It underscores dharma through the grave prohibition against go-hatya (cow-killing) and shows that even royalty can fall in status through adharma and a guru’s curse—reinforcing restraint, protection of dependents, and reverence for teachers.
No Vastu, temple-building, or ritual procedure is specified here; the verse functions as a genealogical transition into the Ikshvaku lineage narrative.
