Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
अथाभिषेकमन्त्रेण वाद्यमङ्गलगीतकैः पूर्णकुम्भेन तेनैव होमान्ते प्रागुदङ्मुखम् //
athābhiṣekamantreṇa vādyamaṅgalagītakaiḥ pūrṇakumbhena tenaiva homānte prāgudaṅmukham //
Then, at the conclusion of the homa, facing east or north, one should perform the consecratory sprinkling (abhiṣeka) with that same full water-pot, accompanied by the abhiṣeka-mantra, musical instruments, and auspicious songs.
This verse is not about pralaya; it prescribes a post-homa consecration (abhiṣeka) rite, emphasizing auspicious performance and correct orientation.
It frames dharmic responsibility as correct ritual execution—after completing a homa, the patron (king/householder) should ensure abhiṣeka is performed with proper mantras, auspicious music, and prescribed directions.
Ritually, it mandates abhiṣeka using a pūrṇakumbha at the homa’s end; architecturally/vaastu-wise, it highlights directional discipline—facing east or north—commonly treated as auspicious for consecration acts.
