Matsya Purana — Characteristics of Dvāpara and Kali Yugas
विद्राव्य सर्वभूतानि चचार वसुधामिमाम् मानवस्य तु वंशे तु नृदेवस्येह जज्ञिवान् //
vidrāvya sarvabhūtāni cacāra vasudhāmimām mānavasya tu vaṃśe tu nṛdevasyeha jajñivān //
Having put all beings to flight, he ranged over this earth; and in this very world he was born in the human lineage, in the line of King Nṛdeva.
This verse does not describe Pralaya directly; it focuses on a dynastic birth in the human (Mānava) line and a kingly figure who subdues beings and traverses the earth.
The verse reflects a royal ideal of establishing order—driving back disruptive forces and moving through the realm—framed within legitimate succession (birth in Manu’s lineage and in Nṛdeva’s line), a key Purāṇic marker of rightful kingship.
No explicit Vāstu, temple-building, or ritual procedure is stated in this verse; its significance is genealogical and political (lineage and territorial movement).
