Srimad Bhagavatam Canto 06, Chapter 18, Text 26

SB 6.18.26

asasanasya tasyedam
 dhruvam unnaddha-cetasah
mada-sosaka indrasya
 bhuyad yena suto hi me
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Diti thought: Indra considers his body eternal, and thus he has become unrestrained. I therefore wish to have a son who can remove Indra’s madness. Let me adopt some means to help me in this.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
One who is in the bodily conception of life is compared in the sastras to animals like cows and asses. Diti wanted to punish Indra, who had become like a lower animal.
