"Intelligence refers to the power to analyze things in their proper perspective...." -Bhagavad-gita 10.4 purport.
"When your intelligence has passed out of the dense forest of delusion, you shall become indifferent to all that has been heard and all that will be heard." -Bhagavad-gita 2.52
"Mind is the center of all the activities of the senses, and thus when we hear about sense objects the mind generally becomes a reservoir of all ideas of sense gratification; and, as a result the mind and the senses become the repositories of lust. Next, the intelligence department becomes the capitol of such lustful propensities. Intelligence is the immediate next-door neighbor of the spirit soul. Lusty intelligence influences the spirit soul to acquire the false ego and identify itself with matter, and thus with the mind and senses. The spirit soul becomes addicted to enjoying the material senses and mistakes this as true happiness." -Bhagavad-gita 3.40 purport.
