Vibhūti-yoga in the Bhāgavata: The Lord’s Manifest Opulences and the Discipline of Control
हिरण्यगर्भो वेदानां मन्त्राणां प्रणवस्त्रिवृत् । अक्षराणामकारोऽस्मि पदानिच्छन्दसामहम् ॥ १२ ॥
hiraṇyagarbho vedānāṁ mantrāṇāṁ praṇavas tri-vṛt akṣarāṇām a-kāro ’smi padāni cchandasām aham
Unter den Veden bin Ich ihr ursprünglicher Lehrer Hiraṇyagarbha (Brahmā); unter den Mantras bin Ich das dreibuchstabige praṇava ‘Oṁ’. Unter den Buchstaben bin Ich ‘a’, und unter den heiligen Metren bin Ich die Gāyatrī.
This verse identifies Krishna as the praṇava (Oṁ) itself—the essence and highest representative among mantras—indicating that sacred sound ultimately points to Bhagavan.
In the Uddhava Gita, Krishna teaches His vibhutis (divine opulences) to help Uddhava perceive the Lord everywhere—especially in Vedic sound, which is a primary doorway to spiritual realization.
By remembering that sacred sound is Krishna’s presence: chant Oṁ or the Lord’s names with attention, study scripture with devotion, and treat speech as sacred by speaking truthfully and beneficially.
