Sanskrit:

श्रीभगवानुवाचत्रिशिरस्ते प्रसन्नोऽस्मि व्येतु ते मज्ज्वराद् भयम् ।यो नौ स्मरति संवादं तस्य त्वन्न भवेद् भयम् ॥ २९ ॥

ITRANS:

śrī-bhagavān uvācatri-śiras te prasanno ’smivyetu te maj-jvarād bhayamyo nau smarati saṁvādaṁtasya tvan na bhaved bhayam

Translation:

The Supreme Lord said: O three-headed one, I am pleased with you. May your fear of My fever weapon be dispelled, and may whoever remembers our conversation here have no reason to fear you.

Purport:

Here the Lord accepts the Śiva-jvara as His devotee and gives him his first order — that he should never frighten, by hot fever, those who faithfully hear this pastime of the Lord’s.
