Srimad Bhagavatam Canto 07, Chapter 01, Text 24

SB 7.1.24

himsa tad-abhimanena
 danda-parusyayor yatha
vaisamyam iha bhutanam
 mamaham iti parthiva
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
My dear King, the conditioned soul, being in the bodily conception of life, considers his body to be his self and considers everything in relationship with the body to be his. Because he has this wrong conception of life, he is subjected to dualities like praise and chastisement.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Only when a conditioned soul accepts the body as himself does he feel the effects of chastisement or praise. Then he determines one person to be his enemy and another his friend and wants to chastise the enemy and welcome the friend. This creation of friends and enemies is a result of one’s bodily conception of life.
