Matsya Purana — Rite and Layout for Consecrating Ponds
सर्वलक्षणसम्पूर्णो मन्त्रविद्विजितेन्द्रियः कुलशीलसमायुक्तः पुरोधाः स्याद्द्विजोत्तमः //
sarvalakṣaṇasampūrṇo mantravidvijitendriyaḥ kulaśīlasamāyuktaḥ purodhāḥ syāddvijottamaḥ //
A royal priest (purohita) should be a foremost Brahmin—complete in all proper qualifications, a knower of mantras, self-controlled in his senses, and endowed with noble lineage and exemplary conduct.
This verse does not address pralaya; it focuses on rajadharma—specifically, the qualifications required for a king’s purohita.
It guides a king’s duty to appoint a competent spiritual adviser: a mantra-knowing, self-restrained, and well-conducted Brahmin, ensuring rituals, counsel, and governance remain aligned with dharma.
The ritual significance is explicit: the purohita must be mantra-vit and self-controlled, implying competence to perform and supervise Vedic rites (yajña, consecrations, royal rituals) correctly and ethically.
