Matsya Purana — Kailasa
मन्दोदकं नाम सरः पयस्तु दधिसंनिभम् तस्मात् प्रवहते दिव्या नदी मन्दाकिनी शुभा //
mandodakaṃ nāma saraḥ payastu dadhisaṃnibham tasmāt pravahate divyā nadī mandākinī śubhā //
There is a lake called Mandodaka, whose water is like curd in appearance; from it flows the divine river Mandākinī, auspicious and sacred.
This verse is not about Pralaya; it is a sacred-geography note describing a holy lake and the auspicious, divine river that flows from it.
Indirectly, it supports the Purāṇic ethic of tīrtha-yātrā and reverence for sacred waters—practices recommended for householders and rulers for merit, purification, and public religious support.
Ritually, it highlights a sanctified water-source suitable for स्नान (snāna, sacred bathing) and offerings; such rivers and lakes are also traditional sites for establishing ghāṭas, shrines, and pilgrimage infrastructure.
