Because we cannot control our senses, we are driving, we are being pushed towards the darkest region of material existence, very hard to leave. Darkest region means that we are going to become animals next life. Because this is animalistic civilization. Nature gave us the opportunity to realize God, but God-realization is meant for human being. The human being, if he does not realize God, he's simply engaged in animalistic way of life—eating, sleeping, mating—then nature will call, "All right, sir, again become animal." Punar mūṣiko bhava: "Again become a mouse." You know this story? Punar mūṣiko bhava. There is a story. There is a very nice story. One rat, mouse, he came to a saintly person. Everyone comes to saintly person for some blessing, you see. Real blessing they don't want. Some material blessing. Real blessing, Kṛṣṇa, they don't want. If you give him some blessing that "You become very rich man and..." These... they'll be very much pleased. are all very well, this. So this mouse also came and begged the saintly person, "Sir, I am in difficulty. If you give me some blessing?"
"What is that?"
"The cat chases after me always. I'm very unhappy."
"So what do you want?"
"Now, if you make me a cat, then I can get relief from this."
"All right, you become cat." So he became cat.
So after few days, again he comes. "Sir, again I am in trouble."
"What is that?"
"The dog is chasing me." (laughter) Don't laugh, hear seriously. "Dog is chasing me."
"All right, then, what do you want?"
"Now, make me a tiger."
"All right, you become a tiger."
So when he became a tiger he was staring on the saintly person like this.
So he asked, "Why you are staring upon me? You want to eat me?"
"Yes."
So he again curses, punar mūṣiko bhava: "Again you become mouse. Again you become mouse."
So that is our position. We are advanced in civilization. Now we want to kill God. So we are again going to be uncivilized, to remain in the forest and to remain naked. Actually, they are practicing that: nature's life. So again they are going to be aborigines. And that is being practiced. They are going to the forest, they remain naked. So actually, punar mūṣiko bhava: "Again become mouse." Civilized human being means God conscious, happy life, no trouble, no enviousness, everything happy, no hard labor. Why hard labor? Everything is there. You just employ your little intelligence, you get sufficient food by grains, by fruits, by flowers, milk. There is no difficulty if we remain in our own way. So that is the difficulty, that we do not know that our ultimate goal of life is God-realization.
