“When we forget our real constitutional position and wish to enjoy the material resources, our material desires manifest, and we associate with varieties of material enjoyment. As soon as the concoctions of material enjoyment are there, because of our association we create a sort of lust or eagerness to enjoy them, and when that false enjoyment does not actually make us happy, we create another illusion, known as anger, and by the manifestation of anger, the illusion becomes stronger. When we are illusioned in this way, forgetfulness of our relationship with Krishna follows, and by thus losing Krishna consciousness, our real intelligence is defeated.” (Shrila Prabhupada, Shrimad Bhagavatam, 4.22.14 Purport)
