Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
अश्वमेधफलं प्राहुर् लक्षहोमं सुरोत्तमाः द्वादशाहमखस् तद्वन् नवग्रहमखः स्मृतः //
aśvamedhaphalaṃ prāhur lakṣahomaṃ surottamāḥ dvādaśāhamakhas tadvan navagrahamakhaḥ smṛtaḥ //
The foremost of the gods declare that a lakh (one hundred thousand) oblations in a homa yields the fruit of an Aśvamedha. Likewise, a twelve-day sacrifice is said to be equivalent; and so too is the Navagraha-sacrifice (Navagraha-makha) regarded.
This verse is not about pralaya; it focuses on ritual equivalences—stating that certain homas and sacrifices are remembered as yielding merit comparable to major Vedic rites like the Aśvamedha.
It offers a dharmic, accessible pathway: instead of undertaking an immense royal rite like the Aśvamedha, a householder or ruler may perform large-scale homa, a twelve-day sacrifice, or a Navagraha-makha to obtain comparable religious merit (phala) within the Purāṇic framework.
The significance is ritual: it ranks and equates major offerings—lakṣahoma (100,000 oblations), a dvādaśāha (twelve-day sattra), and the Navagraha sacrifice—highlighting the importance of graha-propitiation and sustained sacrificial observance.
