Srimad Bhagavatam Canto 06, Chapter 18, Text 71

SB 6.18.71

indra uvaca
amba te ’ham vyavasitam
 upadharyagato ’ntikam
labdhantaro ’cchidam garbham
 artha-buddhir na dharma-drk
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Indra replied: My dear mother, because I was grossly blinded by selfish interests, I lost sight of religion. When I understood that you were observing a great vow in spiritual life, I wanted to find some fault in you. When I found such a fault, I entered your womb and cut the embryo to pieces.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When Diti, Indra’s aunt, explained to Indra without reservations what she had wanted to do, Indra explained his intentions to her. Thus both of them, instead of being enemies, freely spoke the truth. This is the qualification that results from contact with Visnu. As stated in Srimad-Bhagavatam (5.18.12):
 
yasyasti bhaktir bhagavaty akiñcana
 sarvair gunais tatra samasate surah
 
If one develops a devotional attitude and becomes purified by worshiping the Supreme Lord, all the good qualities are certainly manifested in his body. Because of being touched by worship of Visnu, both Diti and Indra were purified.
