Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
तद्वच्च दश चाष्टौ च लक्षहोमे तु ऋत्विजः कर्तव्याः शक्तितस्तद्वच् चत्वारो वा विमत्सरः //
tadvacca daśa cāṣṭau ca lakṣahome tu ṛtvijaḥ kartavyāḥ śaktitastadvac catvāro vā vimatsaraḥ //
Likewise, in a lakh-homa (a rite of one hundred thousand oblations), ten or eight officiating priests (ṛtvijas) should be engaged according to one’s capacity; similarly, even four may be appointed—provided they are free from envy and rivalry.
This verse does not discuss Pralaya directly; it focuses on ritual discipline—specifically how many priests should officiate a large homa and the ethical requirement that they be non-envious.
It guides a patron (king or householder) to appoint ṛtvijas according to resources—ten, eight, or even four—emphasizing character (freedom from jealousy) as essential for a proper sacrifice.
The ritual takeaway is procedural: a lakṣa-homa ideally employs a larger priestly team, but the text permits fewer officiants if necessary, prioritizing competence and harmony (vimatsaratva) among priests.
