We are not perfect, but our knowledge is perfect, because we receive knowledge from the perfect. The same example, that I am not perfect to understand who is my father, but my mother is perfect, and because I accept the perfect knowledge of my mother, therefore my knowledge of father is perfect.
So this Kṛṣṇa consciousness movement is for giving perfect knowledge to the human society: what he is, what is God, what is this material world, why you have come here, why you have to undergo so much tribulations, miserable condition of life, why I die. I do not like to die, but death is compulsory. I do not like to be old man, still, it is compulsory. I do not like to suffer from disease, but it is compulsory. These, these are to be solved. That is really problems of human life. Not that improving the method of eating, sleeping, mating and defending. That is not human life.
A man sleeps; a dog sleeps. So because a man sleeps in a very nice apartment, that does not mean he's advanced more than the dog. The business is sleeping, that's all. Because man has discovered atomic weapon for defending, and the dog has his nails and teeth; he can also defend. So defending is there. You cannot say that, "Because I have got this atomic bomb, therefore I can conquer the whole world or whole universe." That is not possible. You can defend in your own way, and the dog can also defend in his own way.
