atmanam iha sanjatam
janan prag visnuna hatam
yadubhih sa vyarudhyata
atmanam—personally; iha—in this world; sanjatam—born again; janan—understanding well; prak—previously, before this birth; visnuna—by Lord Visnu; hatam—was killed; maha-asuram—a great demon; kalanemim—by the name Kalanemi; yadubhih—with the members of the Yadu dynasty; sah—he (Kamsa); vyarudhyata—acted inimically.
In his previous birth, Kamsa had been a great demon named Kalanemi and been killed by Visnu. Upon learning this information from Narada, Kamsa became envious of everyone connected with the Yadu dynasty.
Persons who are demons, enemies of the Supreme Personality of Godhead, are called asuras. As stated in Bhagavad-gita, the asuras, because of their enmity toward the Supreme Personality of Godhead, take birth after birth in asura families and therefore glide down to the darkest hellish regions.
