Matsya Purana — Genealogy and Classification of Sacred Fires
अनिर्देश्यो ह्यहिर्बुध्न्यो बहिरन्ते तु दक्षिणौ पुत्रा ह्येते तु सर्वस्य उपस्थेया द्विजैः स्मृताः //
anirdeśyo hyahirbudhnyo bahirante tu dakṣiṇau putrā hyete tu sarvasya upastheyā dvijaiḥ smṛtāḥ //
Ahirbudhnya is indeed indescribable; and Bahiranta and Dakṣiṇa are his sons. These two are remembered by the twice-born as deities to be worshipped, being connected with the generative source of all.
Indirectly, it points to cosmic governance through Rudra-linked deities (like Ahirbudhnya), who are often associated with deep foundational powers; the verse itself focuses on worship-worthy divine lineages rather than narrating Pralaya events.
It supports the dharmic duty of reverence (pūjā/upāsanā) toward recognized deities and sacred traditions; for householders and rulers, this translates into maintaining proper worship and honoring the learned (dvijas) who preserve such ritual knowledge.
The ritual takeaway is deity-recognition: Bahiranta and Dakṣiṇa are noted as ‘upastheyāḥ’—fit to be approached and worshipped—useful for structuring stuti, nyāsa, or deity-invocation lists that can later be integrated into temple worship sequences.
