Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
शुक्रं ते अन्यदिति च शुक्रस्यापि निगद्यते शनैश्चरायेति पुनः शं नो देवीति होमयेत् //
śukraṃ te anyaditi ca śukrasyāpi nigadyate śanaiścarāyeti punaḥ śaṃ no devīti homayet //
For Venus, one should recite the mantra beginning “śukraṃ te anyat…”. Then again, for Saturn, (reciting) “śanaiścarāya…”, one should offer oblations into the fire with the mantra “śaṃ no devī…”.
This verse is not about pralaya; it is a practical ritual injunction describing mantra-recitation and homa offerings for pacifying planetary influences (Śukra and Śani).
It frames graha-śānti as a dharmic duty: a householder (and by extension a king responsible for public welfare) maintains auspiciousness and removes impediments through prescribed mantras and homa, aligning personal and social order with ritual discipline.
The significance is ritual: it specifies which mantras are to be recited for Venus and Saturn and that oblations should be offered with the “śaṃ no devī…” mantra—an explicit homa-vidhi detail used in planetary pacification rites.
