SB 5.6.8
atha samira-vega-vidhuta-venu-vikarsana-jatogra-davanalas tad vanam alelihanah saha tena dadaha.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
While He was wandering about, a wild forest fire began. This fire was caused by the friction of bamboos, which were being blown by the wind. In that fire, the entire forest near Kutakacala and the body of Lord Rsabhadeva were burnt to ashes.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Such a forest fire can burn the external bodies of animals, but Lord Rsabhadeva was not burned, although He apparently seemed so. Lord Rsabhadeva is the Supersoul of all living entities within the forest, and His soul is never burned by fire. As stated in Bhagavad-gita, adahyo ’yam — the soul is never burned by fire. Due to Lord Rsabhadeva’s presence, all the animals in the forest were also liberated from material encagement.
