SB 4.28.11, Translation and Purport:

Under the circumstances, the elder brother of Yavana-rāja, known as Prajvāra, set fire to the city to please his younger brother, whose other name is fear itself.

According to the Vedic system, a dead body is set on fire, but before death there is another fire, or fever, which is called prajvāra, or viṣṇu-jvāra. Medical science verifies that when one's temperature is raised to 107 degrees, a man immediately dies. This prajvāra, or higher fever, at the last stage of life places the living entity in the midst of a blazing fire.
