Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
हुत्वा च तांश्चरून्सम्यक् ततो होमं समाचरेत् आकृष्णेति च सूर्याय होमः कार्यो द्विजन्मना //
hutvā ca tāṃścarūnsamyak tato homaṃ samācaret ākṛṣṇeti ca sūryāya homaḥ kāryo dvijanmanā //
Having properly offered those ritual rice-cakes (caru) into the fire, one should then duly perform the homa. A twice-born person should make the fire-offering to Sūrya, reciting the formula beginning with “ā-kṛṣṇa…”.
This verse is not about pralaya; it prescribes a precise ritual sequence—first offering the caru oblations, then performing a Sūrya-directed homa with a specified mantra incipit.
It frames disciplined ritual action as dharma: a qualified ‘dvija’ (including householders among the twice-born) should perform ordered homa rites, reflecting daily/occasional obligations and purity of procedure.
The significance is ritual (not architectural): it stresses correct sequencing (caru first, homa next) and mantra-specific offering to Sūrya—key for accurate homa performance in Purāṇic ritual manuals.
