Śrīla Prabhupāda Says

Regarding real intelligence means that we understand that we can never satisfy ourselves or our senses and so try and satisfy Kṛṣṇa

So this is intelligence, that I have to serve. Now in my material condition I am serving so many things, especially my senses. So neither my senses are satisfied ­nor I am satisfied. So this intelligence is not coming to us. They are going on, carvita-carvaṇānām, chewing the chewed. The senses, same sense gratification in different way.

     In theatre, in stage, in, at home, at club—everywhere. Simply changing the platform and trying to be happy. How you can be happy? They already distasted. Does it mean that sense satisfaction in an apartment and sense satisfaction in the club is different? It is simply imagination. "Let me go to the club, let me go to the stage, let me go to this Florida beach, and let me go there, let me see the naked dance, let me see that, let me..." That's all.

     But the platform is there, sense gratification. But he is not intelligent that "I have satisfied my senses in so many different ways. I have served my senses in so many different ways. Neither I am satisfied, neither my senses are satisfied."

     Therefore the intelligent man says, "I am no more going to satisfy my senses, I will satisfy Kṛṣṇa." That is Kṛṣṇa consciousness. Then he gets full satisfaction. This is voluntary. This is called surrender, that "I have tried to satisfy my, the whims of my senses so many lives. I have become frustrated, confused. Let me try this life to satisfy the senses of Kṛṣṇa." That's all. At least let me give a trial one life, and let me see the result.
