So nature will say, “All right, again you become monkey.”

The birds and beasts, they are also doing the same thing. In the morning they find out any tree, anywhere they stop, and small fruits they can eat. So the eating arrangement is already there, although they have no kitchen or hotel. The eating arrangement is there. And then sleeping: they have got a small nest. Or without nest, they sit down on the top of the tree and sleep. Eating, sleeping, and mating, sex. There is always a pair, one male, one female. They are born like that. The sex is there. Eating is there, sleeping is there, and being afraid of other animals, that is also there. As soon as they are little afraid, immediately the sparrow goes up to the… You cannot catch him. So these things are there even in the animal life, lower grade of life. But is that human life is also meant for that, the same thing? There is no other aim of life? No. That they do not know. Therefore sastra says, na te viduh svartha-gatim hi visnum [SB 7.5.31] They do not know what is the aim of life.

The aim of life is how to become free from these clutches of maya, repetition of birth and death. That is the aim of life.

mam upetya kaunteya duhkhalayam asasvatam napnuvanti mahatmanah samsiddhim paramam gatah [Bg. 8.15]

This is aim of life. One has to become mahatma, greater soul, great soul, must understand. So therefore there must be training. Without training, how… Because after all, we are coming from the lower grade of life, animal life, and they are very expert scientist that “Man is coming from monkey.” That’s all right, but shall you remain a monkey or you shall become a better person than the monkey? But they have preferred to remain as monkey. That’s all. When there is impotency, they borrow glands from the monkey for increasing their sex appetite. That means again going to the monkey. Punar musiko bhava. There is a story that a mouse approached a saintly person. “Sir, I have come to you for some favor.” “What is that?” “Now, I am mouse. The cats gives me much trouble. I cannot live peacefully on account of the cats.” So the saintly person asked, “What do you want to become?” “I want to become a cat.” “All right, you become a cat.” Then after some time he again came: “Sir, I am still bothered.” “Why?” “The dogs, they bother me.” “Then what do you want?” “Now, let me become a dog.” “All right, you become a dog.” Then again after some time he came back, that “Still they bother me, sir.” “What do you want?” In this way, after, one after, he, at last he begged the saintly person to become a tiger. So the saintly person, “All right, you become a tiger.” Then, when he became tiger, he began to stare his eyes on the saintly person. The saintly person, “What do you mean by this?” “I shall eat you.” “Oh, you shall eat me? All right. Punar musiko bhava: Again you become a mouse. I have made you tiger, and you want to eat me. So you become again mouse.”

So our civilization is like that, that in the gradual process of evolution we have come to the platform of human being. This human being is meant for understanding God, but they are forgetting God. Therefore the next stage is punar musiko bhava, “Again become monkey.” That is waiting us. The nature’s law is like that, that from monkey we have become human being, and in the human being we are dancing like monkey. So nature will say, “All right, again you become monkey.” You cannot check that. That is not possible. Daivi hy esa guna-mayi mama maya duratyaya. This nature’s process is going on, but we are so advanced scientist that we do not know how nature is working. Automatically working. Nature’s way of working is automatic. Just like you have got so many automatic machine, similarly, this is, this machine is made by the Supreme Lord. It is perfect machine, one after another, one after another. So just like if you infect some disease, nature’s way, you will develop that disease. That is the way. Karanam guna sango ’sya sad-asad janma-yonisu. This is stated. Now we have got this nice human form of body, but if we associate with the low-grade qualities of this material world—means tamo-guna—then again we are going to become animal automatically. They do not know it. They are thinking, “I am enjoying life by eating meat and drinking wine and having illicit sex and gambling. It is very joyful life.” But he does not know that he is associating with tamo-guna, and he is going to be an animal, cats and dogs and monkey. This is a fact.
