Matsya Purana — Rite and Layout for Consecrating Ponds
तथाङ्गुल्यः पवित्राणि वासांसि विविधानि च पूजयेत्तु समं सर्वान् आचार्यो द्विगुणं पुनः दद्याच्छयनसंयुक्तम् आत्मनश्चापि यत्प्रियम् //
tathāṅgulyaḥ pavitrāṇi vāsāṃsi vividhāni ca pūjayettu samaṃ sarvān ācāryo dviguṇaṃ punaḥ dadyācchayanasaṃyuktam ātmanaścāpi yatpriyam //
Likewise, one should honor all the invited recipients equally with rings and sacred threads (pavitra), and with various garments. But to the teacher (ācārya) one should again give double, and also present a bed with its furnishings—indeed, whatever is dear to oneself.
This verse does not discuss pralaya; it focuses on dharma in ritual conduct—how offerings and gifts should be distributed, especially prioritizing the ācārya.
It frames a key householder/ritual duty: honor all qualified recipients without partiality, yet give special, doubled honor (dakṣiṇā) to one’s teacher, even offering valuable personal items.
Ritually, it lists standard pūjā/dāna items—rings, sacred threads, garments—and prescribes gifting a complete bed-set (śayana-saṃyukta), indicating completeness and respect in ceremonial donation.
