Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

By transformation of the false ego in passion, intelligence takes birth, O virtuous lady. The functions of intelligence are to help in ascertaining the nature of objects when they come into view, and to help the senses.

 

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

Intelligence is the discriminating power to understand an object, and it helps the senses make choices. Therefore intelligence is supposed to be the master of the senses. The perfection of intelligence is attained when one becomes fixed in the activities of Krsna consciousness. By the proper use of intelligence one’s consciousness is expanded, and the ultimate expansion of consciousness is Krsna consciousness.f
