एतद् रहस्यं परम॑ ब्रह्मणो हृदि संस्थितम् । ब्रह्मा प्रोवाच शक्राय शक्र: प्रोवाच मृत्यवे,यह परम रहस्यमय स्तोत्र ब्रह्माजीके हृदयमें स्थित है। ब्रह्माजीने इन्द्रको इसका उपदेश दिया और इन्द्रने मृत्युको
etad rahasyaṁ paramaṁ brahmaṇo hṛdi saṁsthitam | brahmā provāca śakrāya śakraḥ provāca mṛtyave |
Vāyu said: “This supreme secret—an inner mystery resting in Brahmā’s own heart—was first taught by Brahmā to Śakra (Indra), and Śakra in turn taught it to Mṛtyu (Death).”
वायुदेव उवाच
That the doctrine being introduced is a “supreme secret” preserved in a sacred lineage; its authority and efficacy are grounded in careful transmission from Brahmā to Indra to Mṛtyu, implying it should be approached with reverence, restraint, and ethical responsibility.
