Matsya Purana — Prologue to the Matsya Purana and the Manu–Pralaya Rescue Narrative
दृष्ट्वा तच्छफरीरूपं स दयालुर्महीपतिः रक्षणायाकरोद्यत्नं स तस्मिन्करकोदरे //
dṛṣṭvā tacchapharīrūpaṃ sa dayālurmahīpatiḥ rakṣaṇāyākarodyatnaṃ sa tasminkarakodare //
Seeing it in the form of a small fish, that compassionate king made an effort to protect it, placing it there in the hollow of his hand.
It sets the ethical prelude to the Pralaya narrative: Manu’s compassionate protection of the fish (Matsya) becomes the trigger for the later revelation about the coming deluge.
It highlights rājadhrama through dayā (compassion): a king should protect the vulnerable, even a small creature, showing readiness to shelter those seeking refuge.
No Vāstu or ritual procedure is stated directly; the focus is on protective conduct (rakṣaṇa) as a foundational dharmic act preceding the Matsya revelation.
