Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
चान्द्रायणं च यः कुर्याद् धैमं चन्द्रं निवेदयेत् चन्द्रव्रतमिदं प्रोक्तं चन्द्रलोकफलप्रदम् //
cāndrāyaṇaṃ ca yaḥ kuryād dhaimaṃ candraṃ nivedayet candravratamidaṃ proktaṃ candralokaphalapradam //
Whoever performs the Cāndrāyaṇa observance and offers a golden image of the Moon—this is declared to be the Candravrata (Moon-vow), bestowing as its fruit attainment of the Moon’s world (Candraloka).
This verse is not about Pralaya; it focuses on vrata-dharma, stating that a specific lunar penance and offering yields the posthumous fruit of Candraloka.
It presents a householder-accessible religious duty: performing the Cāndrāyaṇa observance and making a prescribed dāna (offering a golden Moon image), linking disciplined conduct and charity with a defined spiritual result.
Ritually, it prescribes a vow plus an iconic offering (a golden representation of Chandra), highlighting the Purāṇic use of pratima-dāna (image-gift) as a merit-producing rite.
