What is the difference between animal and man? The animal cannot be instructed anything about God. It is not possible for them to understand. But a man, however degraded he may be, if he is trained up, he can understand about God. Just like five years ago, you did not know about Kṛṣṇa. But because you are being trained up, because you are human being, therefore you are taking to Kṛṣṇa consciousness. Which was unknown to you five years ago, now you are taking it to very seriously. Why? Because you are being trained up.
Similarly, God consciousness is there, dormant in every living entity. But the perception varies according to the development of body. Just like child. You say something serious, say, about sex life, they do not understand. But the same child will understand sex life when the consciousness is developed. Similarly, in this material world, our consciousness is covered, God consciousness. So there are different species of life. Just like the aquatics in the ocean. There are so many living entities. But if you preach there Kṛṣṇa consciousness, it is not possible Their number is far greater than human being. Still, they have no capacity. Next development, plants and trees, there also, no sensation. You cut the trees, no protest, because there is no sensation. There is practically consciousness... There is consciousness, very slight. Sir Jagadish Candra Bose has proved that when you cut tree, he feels, and that is recorded in what is called, that machine? So everyone has got consciousness. Living entity means there is consciousness. But they have their consciousness only for eating, sleeping, sex life and defending. There is consciousness amongst the fish. Their consciousness is so strong, two miles away if some big fish is coming, they can understand. Immediately they can take precaution defending. These are all described. So different animals in different species of life, they have got one type of consciousness very strong.
