SB 11.25.11
yada asisa asasya
mam bhajeta sva-karmabhih
tam rajah-prakrtim vidyat
himsam asasya tamasam
Translation:
When a person worships Me by his prescribed duties with the hope of gaining material benefit, his nature should be understood to be in passion, and one who worships Me with the desire to commit violence against others is in ignorance.
