Matsya Purana — Kailasa
सोमपादात्प्रसूता सा सप्तधा प्रविभज्यते यूपा मणिमयास्तत्र विमानाश्च हिरण्मयाः //
somapādātprasūtā sā saptadhā pravibhajyate yūpā maṇimayāstatra vimānāśca hiraṇmayāḥ //
Born from Soma’s quarter called Somapāda, that formation is divided into seven parts. In that arrangement, the sacrificial posts (yūpas) are made of gems, and the vimānas—celestial edifices—are made of gold.
This verse does not describe pralaya directly; it focuses on a sevenfold architectural/ritual classification and the auspicious materials (gems and gold) used for yūpas and vimānas.
It supports the dharmic duty of sponsoring yajña and sacred construction: a king or affluent householder is encouraged to uphold ritual order and merit through properly made yūpas and well-appointed vimānas.
It links ritual and architecture by specifying prestigious materials—gem-made yūpas (sacrificial posts) and gold-made vimānas—within a sevenfold division, implying graded typologies and material prescriptions in Matsya Purana vastuvidya.
