Matsya Purana — The Madana-Dvādaśī Vow and the Birth of the Maruts
शय्यां दद्यादनङ्गाय सर्वोपस्करसंयुताम् काञ्चनं कामदेवं च शुक्लां गां च पयस्विनीम् //
śayyāṃ dadyādanaṅgāya sarvopaskarasaṃyutām kāñcanaṃ kāmadevaṃ ca śuklāṃ gāṃ ca payasvinīm //
One should offer to Ananga (Kāma) a bed furnished with all its accessories, together with a golden image of Kāmadeva, and also a white cow that yields milk.
This verse does not discuss pralaya; it focuses on dāna-dharma—meritorious gifting as a means of sustaining dharma and auspicious order in worldly life.
It prescribes a specific charitable act: a householder (and by extension a king as chief patron) should donate well-appointed comforts (a furnished bed), a valuable devotional object (a golden Kāmadeva), and a productive asset (a milk-giving cow), reflecting responsible wealth-use and ritual generosity.
The significance is ritual rather than architectural: it outlines the proper constituents of a formal gift—completeness of the donated item (bed with accessories) and suitability of the offering (golden deity-image and a healthy, milk-yielding white cow).
