tasya murdhnah samudbhutah
sadhumo ’gnis tapomayah
tiryag urdhvam adho lokan
pratapad visvag iritah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Because of Hiranyakasipu’s severe austerities, fire came from his head, and this fire and its smoke spread throughout the sky, encompassing the upper and lower planets, which all became extremely hot.
