Matsya Purana — Rites for Consecrating and Celebrating Trees
हेमसूत्रैः सकटकैर् अङ्गुलीयपवित्रकैः वासोभिः शयनीयैश्च तथोपस्करपादुकैः क्षीरेण भोजनं दद्याद् यावद्दिनचतुष्टयम् //
hemasūtraiḥ sakaṭakair aṅgulīyapavitrakaiḥ vāsobhiḥ śayanīyaiśca tathopaskarapādukaiḥ kṣīreṇa bhojanaṃ dadyād yāvaddinacatuṣṭayam //
With golden threads, small carts, rings and sacred finger-rings, garments and bedding, as well as household utensils and footwear—one should offer food prepared with milk for a full four days.
This verse does not discuss pralaya; it focuses on dāna-dharma—material gifts and a four-day milk-based feeding observance.
It outlines a householder-style duty of charity: donating useful goods (clothing, bedding, utensils, footwear, ritual items) and sustaining a feeding offering for four days—an ideal also applicable to royal patronage.
The ritual significance is the prescribed dāna list (including pavitraka ritual rings) and the specific duration—four days—of offering milk-based food, indicating a structured vow/feeding rite rather than Vāstu or temple-building rules.
