SB 10.63.29

sri-bhagavan uvaca
tri-siras te prasanno ’smi
 vyetu te maj-jvarad bhayam
yo nau smarati samvadam
 tasya 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 Siva-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.
