Matsya Purana — The Maheshvara Vow: Śiva-Caturdaśī Vrata
ताम्रपात्रोपरि पुनः शालितण्डुलसंयुतम् स्थाप्य विप्राय शान्ताय वेदव्रतपराय च //
tāmrapātropari punaḥ śālitaṇḍulasaṃyutam sthāpya viprāya śāntāya vedavrataparāya ca //
Again, placing the offering upon a copper vessel together with grains of rice, one should present it to a peaceful brāhmaṇa—one devoted to Vedic observances and sacred vows.
This verse does not discuss pralaya; it focuses on dharma—specifically the correct procedure for making a gift (dāna) using a copper vessel and rice, and the proper recipient.
It instructs the giver (especially a householder, and by extension a king who performs public charity) to make offerings in a ritually proper manner and to choose a worthy recipient: a calm, self-disciplined brāhmaṇa devoted to Vedic vows.
The ritual takeaway is the prescribed offering protocol: placing the gift on a copper vessel (tāmra-pātra) along with rice grains, emphasizing purity, correct materials, and eligibility of the recipient.
