Srimad Bhagavatam Canto 04, Chapter 19, Text 35

SB 4.19.35

kratur viramatam esa
devesu duravagrahah
dharma-vyatikaro yatra
pakhandair indra-nirmitaih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
 
Lord Brahma continued: Stop the performance of these sacrifices, for they have induced Indra to introduce so many irreligious aspects. You should know very well that even amongst the demigods there are many unwanted desires.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
 
There are many competitors in ordinary business affairs, and the karma-kanda chapters of the Vedas sometimes cause competition and envy amongst karmis. A karmi must be envious because he wishes to enjoy material pleasures to their fullest extent. That is the material disease. Consequently there is always competition amongst karmis, either in ordinary business affairs or in the performance of yajña. Lord Brahma’s purpose was to end the competition between Lord Indra and Maharaja Prthu. Because Maharaja Prthu was a great devotee and incarnation of God, he was requested to stop the sacrifices so that Indra might not further introduce irreligious systems, which are always followed by criminal-minded people.
