Prabhupāda: Just like if you are taking service from your car, so you don't identify yourself with the car. But you take care of the car to take service from it.
Similarly, we are taking service from this body because we are living, so I must eat or I must sleep. It is not that we are not eating or not sleeping, but our eating is different from ordinary eating. We discriminate eating. We don't eat so many things. We simply eat things which may keep my body just fit for understanding and executing this mission of life. That's all.
Let's take for example we don't take meat, we don't take eggs, fish, we don't take liquor or any sorts of intoxicants, even up to the cigarette, coffee, tea, because we know these things are superfluous. Nobody learns to smoke from the beginning of life, but the child requires to eat something. That's a fact. But it doesn't require to smoke. So these are artificial things. So we have to minimize the non-necessary things.
Interviewer: But does the child, for example, require to achieve Kṛṣṇa consciousness?
Prabhupāda: Yes. Every human being is given the chance by nature's way. You are given this human form of body, civilized man with developed consciousness, to understand these problems of your life. The animals cannot understand. You have come here because you are human being. The dog is not coming, the cat is not coming, because they are animals. So this Kṛṣṇa consciousness movement is for the human being.
