Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
हरिताश्वस्य दिक्पूर्वा विश्रुता कुरुभिः सह प्रतिष्ठाने ऽभिषिच्याथ स पुरूरवसं सुतम् //
haritāśvasya dikpūrvā viśrutā kurubhiḥ saha pratiṣṭhāne 'bhiṣicyātha sa purūravasaṃ sutam //
Then, in Pratiṣṭhāna, he consecrated his son Purūravas by royal anointing and installed him as king—together with the Kurus—while the eastern quarter (of Haritāśva) was renowned.
This verse does not discuss Pralaya; it belongs to the dynastic narrative, focusing on royal consecration and lineage geography.
By highlighting abhiṣeka (royal consecration) performed publicly and with recognized groups (the Kurus), it reflects the Purāṇic ideal that kingship is a sanctioned office tied to legitimacy, lineage, and orderly succession.
The key ritual element is abhiṣeka (anointing/consecration) conducted at Pratiṣṭhāna, indicating a formal enthronement setting associated with established political-ritual centers.
