SB 6.18.26

āśāsānasya tasyedaṁ
 dhruvam unnaddha-cetasaḥ
mada-śoṣaka indrasya
 bhūyād yena suto hi me
Word for word: 
āśāsānasya — thinking; tasya — of him; idam — this (body); dhruvam — eternal; unnaddha-cetasaḥ — whose mind is unrestrained; mada-śoṣakaḥ — who can remove the madness; indrasya — of Indra; bhūyāt — may there be; yena — by which; sutaḥ — a son; hi — certainly; me — of me.
Translation: 
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: 

One who is in the bodily conception of life is compared in the śāstras to animals like cows and asses. Diti wanted to punish Indra, who had become like a lower animal.
