If one is addicted to this material way of life, he cannot understand, or cannot be convinced, about Kṛṣṇa consciousness. In the Bhagavad-gītā also, it is said that,
- bhogaiśvarya-prasaktānāṁ
- tayāpahṛta-cetasāṁ
- vyavasāyātmikā buddhiḥ
- samādhau na vidhīyate
- (BG 2.44)
Those who are too much attached for materialistic way of life—means sense gratification... Materialistic way of life means sense gratification. What is the difference between spiritual life and material life? These boys, these boys from Europe and America, they have adopted this spiritual life means they have stopped the process of sense gratification—no illicit sex, no meat-eating, no gambling, no intoxication. This is materialistic way of life. Otherwise, where is the difference between this life and that life?
So if we stick to the materialistic way of life, it will be very, very difficult to understand this Kṛṣṇa consciousness movement. Matir na kṛṣṇe parataḥ svato vā mitho 'bhipadyeta gṛha-vratānām (SB 7.5.30). Why? Now, adānta-gobhiḥ. Adānta means uncontrolled. Uncontrolled. Our senses are uncontrolled. This morning, when I was walking on the beach, we found so many things—the capsule of the Coca-cola, cigarette butts and so many other things. So what is the necessity of this Coca-cola? You don't find all these things in our Society. We don't drink Coca-cola. We don't drink Pepsi-cola. We don't smoke. So many things which are selling in the market in huge quantity by advertisement, by victimizing the poor customer... But they are called unnecessary things. There is no need of such things. But adānta-gobhiḥ, because the senses cannot be controlled, they are making business. They are making business, unnecessary thing. So we have to control the senses. If we really want spiritual life, if we really want to be freed from these material clutches, then we have to learn how to control the senses. That is wanted. That is the purpose of human life. Now... That is the purpose of human life. Human life is not meant for imitating the life of cats and dogs and hogs. That is not human life.
