Matsya Purana — Rites for Consecrating and Celebrating Trees
यद्यदिष्टतमं किंचित् तत्तद् दद्यादमत्सरी आचार्ये द्विगुणं दद्यात् प्रणिपत्य विसर्जयेत् //
yadyadiṣṭatamaṃ kiṃcit tattad dadyādamatsarī ācārye dviguṇaṃ dadyāt praṇipatya visarjayet //
यद्यदिष्टतमं किंचिदल्पमपि, अमत्सरी जनः तदेव दद्यात्। आचार्याय तु द्विगुणं दद्यात्, प्रणिपत्य च सादरं विसर्जयेत्॥
This verse does not discuss pralaya; it teaches dana-dharma—how giving should be done without envy, emphasizing inner purity over cosmological themes.
It frames charity as a disciplined duty: give sincerely (even what one values most), remain free of jealousy, honor the teacher with greater generosity, and maintain humility—principles applicable to both royal patronage and household giving.
No Vastu or temple-construction rule is stated; the ritual etiquette implied is respectful conduct toward the ācārya—offering, bowing, and departing properly as part of dharmic practice.
