People cannot understand. We are changing. "Child is the father of man." So the same child, he has become now father, but he's not talking nonsense now because the body has changed. The child is talking so many nonsense things. People laugh, enjoy. But if the father talks nonsense, then he'll be called, "Here is a rascal." So because the body has changed. So in this way, body is being changed. The child is becoming father; the body has changed. Still, you cannot understand how the change of body, transformation of the body, does not make any transformation of the owner of the body. Dehino 'smin yathā dehe kaumāraṁ yauvanam (BG 2.13). He is there, but according to the body he is behaving differently. When he's in the cat's body, he's behaving differently. When he's in a dog's body, he's behaving differently. When he's human body, he's behaving differently. When he's child's body . . . This is all due to the body.
So therefore, when we come to the full-fledged human form of life, developed consciousness, we must utilize it, as it is advised by Kṛṣṇa Himself, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65): "Always think of Me," man-manā. And who can think of Kṛṣṇa unless he's devotee? Man-manā bhava mad-bhakto. Who is nondevotee, he'll think of something else: "Why I think of Kṛṣṇa?" Therefore to stick to this principle, to apply the mind always in Kṛṣṇa, that means he's devotee. This is devotee. Devotee means not with four hands or four legs. No. The hands, legs are the same, but his mode of thinking different. That's all. That is devotee. Devotee does not depend on the country, color or religion or circumstance. Devotee means the mind. Anyone who is always thinking of Kṛṣṇa, he is devotee. That is the first qualification of devotee. Man-manā bhava mad-bhakto. Therefore we have to practice. Abhyāsa yoga-yuktena . . . (BG 8.8). This is called abhyāsa. Mind is going out of my control. I want to think of Kṛṣṇa, but mind is thinking something else. This is called yoga practice. So we have to catch again mind: "Why you are going there? Come here. Think of Kṛṣṇa." Then that is practice. That is called yoga. You cannot allow the mind. And when you can control the mind . . . Generally, we are controlled by the mind. That is the position of our conditional life.
