Matsya Purana — The Sun-Vow
अर्घ्यं दत्त्वा विसृजाथ निशि तैलविवर्जितम् भुञ्जीत वत्सरान्ते तु काञ्चनं कमलोत्तमम् पुरुषं च यथाशक्त्या कारयेद्द्विभुजं तथा //
arghyaṃ dattvā visṛjātha niśi tailavivarjitam bhuñjīta vatsarānte tu kāñcanaṃ kamalottamam puruṣaṃ ca yathāśaktyā kārayeddvibhujaṃ tathā //
Having offered arghya (the respectful water-offering), one should release (conclude) the observance at night and take a meal free from oil. At the end of the year, one should, according to one’s means, commission a golden lotus of excellent form, and also have a two-armed figure of a man made likewise.
This verse is not about Pralaya; it focuses on vrata-ritual procedure—offering arghya, ending the observance at night, dietary restraint (oil-free food), and prescribed year-end gifts.
It outlines a dharmic observance: disciplined conduct (regulated eating) and dāna (charitable commissioning of sacred objects) at the completion of a yearly vow—duties applicable to householders and rulers alike as patrons of ritual and charity.
Ritually, it prescribes arghya and the proper conclusion of a vow, plus an oil-free meal; iconographically, it specifies commissioning a golden lotus and a dvibhuja (two-armed) human figure—suggesting standardized sacred gift-objects/mūrti forms used in Purāṇic worship and dāna.
