Matsya Purana — The Rite of the Jaggery-Cow
नवनीतेन रत्नैश्च तथान्ये तु महर्षयः एतदेवंविधानं स्यात् त एवोपस्कराः स्मृताः //
navanītena ratnaiśca tathānye tu maharṣayaḥ etadevaṃvidhānaṃ syāt ta evopaskarāḥ smṛtāḥ //
With fresh butter (navanīta) and with gems (ratna)—and likewise with other such offerings, O great sages—when the procedure is of this kind, these very items are traditionally remembered as the requisite implements (upaskaras) for the rite.
This verse does not discuss pralaya; it focuses on classifying certain offerings/materials (like butter and gems) as recognized ritual requisites (upaskaras).
It supports the duty of proper, rule-based worship and patronage: a king or householder should provide prescribed materials for rites and consecrations, treating them as essential requisites rather than optional luxuries.
It defines items such as fresh butter and gems (and similar materials) as upaskaras—standard requisites used to complete rituals associated with sacred works, including temple/altar rites and related consecratory procedures.
