Sanskrit:

विद्राविते भूतगणे ज्वरस्तु त्रिशिरास्‍त्रीपात् ।अभ्यधावत दाशार्हं दहन्निव दिशो दश ॥ २२ ॥

ITRANS:

vidrāvite bhūta-gaṇejvaras tu trī-śirās trī-pātabhyadhāvata dāśārhaṁdahann iva diśo daśa

Translation:

After Lord Śiva’s followers had been driven away, the Śiva-jvara, who had three heads and three feet, pressed forward to attack Lord Kṛṣṇa. As the Śiva-jvara approached, he seemed to burn everything in the ten directions.

Purport:

Śrīla Viśvanātha Cakravartī quotes the following description of the Śiva-jvara: “The terrible Śiva-jvara had three legs, three heads, six arms and nine eyes. Showering ashes, he resembled Yamarāja at the time of universal annihilation.”
