Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
संयोज्य मन्त्रमेवाथ पर्णाशाजलमस्पृशत् तदोपस्पर्शनात्तस्य चकार प्रियमापगा //

Then, having duly applied the mantra, he touched the water taken in a leaf-cup; and by that sanctifying contact, the river—the flowing waters—became well-disposed and granted him a favorable response.
It shows the ritual preconditions—mantra-charged water and sanctifying touch—by which cosmic events are approached in the narrative; the Pralaya episode is framed as unfolding alongside properly performed sacred rites rather than as a random catastrophe.
It highlights a core puranic ethic: disciplined mantra-practice and ritual purity. A ruler or householder is expected to perform rites correctly, using consecrated water, so that natural and divine forces become ‘favorable’ (priya) and support dharmic aims.
Ritually, it points to mantra-siddha water used for purification/sprinkling (prokṣaṇa) and auspicious initiation of actions; the leaf-cup (parṇāśā) detail reflects prescribed ritual implements—an approach echoed in Matsya Purana’s broader procedural rules (use of sanctified water before consecrations).
