Ṛग्विधानम् (Ṛgvidhāna) — Applications of Ṛgvedic Mantras through Japa and Homa
आदित्येत्यृक् च सम्राजं जप्त्वा वादे जयी भवेत् महीति च चतुष्केण मुच्यते महतो भयात्
ādityetyṛk ca samrājaṃ japtvā vāde jayī bhavet mahīti ca catuṣkeṇa mucyate mahato bhayāt
“আদিত্য …” দিয়ে আরম্ভ ঋচা এবং “সম্রাজ” মন্ত্র জপ করলে বিতর্কে বিজয়ী হয়। আর “মহী …” চারবার পাঠ করলে মহাভয় থেকে মুক্তি লাভ হয়।

Sandhi Resolution Notes: आदित्येत्यृक् = आदित्य + इति + ऋक्; भवेत् महीति = भवेत् + मही + इति.
It teaches specific mantra-prayoga: japa of the “Āditya…” ṛk with the “Samrāj” mantra for victory in debate, and a fourfold recitation of the “Mahī…” mantra for protection from great fear.
Alongside theology and cosmology, the Agni Purana catalogs practical, outcome-oriented applications of Vedic material—here, using named ṛks/mantras as prescriptive tools for social success (vāda-jaya) and crisis-protection (bhaya-nivṛtti).
The verse frames disciplined japa as a means of invoking protective and empowering sacred speech (mantra-śakti), yielding both worldly benefit (victory) and purification/relief from fear through reliance on Vedic recitation.
