Matsya Purana — Phala-Saptamī Vow
इमामनन्तफलदां यः कुर्यात्फलसप्तमीम् सर्वपापविशुद्धात्मा सूर्यलोके महीयते //
imāmanantaphaladāṃ yaḥ kuryātphalasaptamīm sarvapāpaviśuddhātmā sūryaloke mahīyate //
Whoever performs this Phala-saptamī—bestowing endless results—becomes purified of all sins and is honored in the realm of the Sun.
This verse does not address Pralaya; it focuses on the fruit (phala) of a specific vrata, emphasizing purification and attainment of honor in Sūrya-loka.
It presents a practical dharma-path: by observing a prescribed vrata (Phala-saptamī), a householder (and likewise a ruler seeking personal and public auspiciousness) gains moral purification and religious merit, reinforcing ethical self-discipline through ritual duty.
The significance is ritual rather than architectural: the verse highlights the performance of Phala-saptamī on Saptamī tithi as a merit-producing observance leading to sin-cleansing and solar-world honor.
