ततो देवाधिदेव: स योगात्मा योगसारथि: । योगमास्थाय भगवांस्तदा भरतसत्तम,भरतश्रेष्ठ) इसके बाद योगस्वरूप योगके नियन्ता देवाधिदेव भगवान्‌ वाराह दैत्यों और दानवोंको क्षोभमें डालनेके लिये योगका आश्रय ले बड़े जोर-जोरसे गर्जना करने लगे। उस भीषण गर्जनासे तीनों लोक और ये सारी दसों दिशाएँ गूँज उठीं

tato devādhidevaḥ sa yogātmā yogasārathiḥ | yogam āsthāya bhagavāṁs tadā bharatasattama ||

Bhishma said: “Then that Lord of lords—whose very nature is Yoga and who guides Yoga as a charioteer—entered into Yoga. At that time, O best of the Bharatas, the Blessed One assumed yogic power and began to roar mightily, shaking and unsettling the hosts of Daityas and Danavas. By that dreadful roar, the three worlds and all the ten directions resounded.”

Educational Q&A

The verse presents Yoga not merely as personal discipline but as sovereign divine power: the Supreme Lord ‘takes refuge in Yoga’ to uphold cosmic order. Ethically, it implies that true power is governed by inner mastery and is exercised to restrain disruptive forces (symbolized by Daityas and Danavas) and protect the worlds.

Bhishma describes the Supreme Lord (contextually Varāha) entering a yogic state and roaring with immense force. The roar terrifies and destabilizes the demonic hosts and reverberates through the three worlds and all directions, signaling divine intervention and the reassertion of order.
