Srimad Bhagavatam Canto 04, Chapter 28, Text 11

SB 4.28.11

bhaya-namno ’grajo bhrata
 prajvarah pratyupasthitah
dadaha tam purim krtsnam
 bhratuh priya-cikirsaya
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Under the circumstances, the elder brother of Yavana-raja, known as Prajvara, set fire to the city to please his younger brother, whose other name is fear itself.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
According to the Vedic system, a dead body is set on fire, but before death there is another fire, or fever, which is called prajvara, or visnu-jvara. Medical science verifies that when one’s temperature is raised to 107 degrees, a man immediately dies. This prajvara, or high fever, at the last stage of life places the living entity in the midst of a blazing fire.
