There are many examples. Just like in a nice cage, in a golden cage, there is a bird. If you don't give any food to the bird and simply wash the cage very nicely, oh, there will be always, (imitates bird) "chi chi chi chi chi." Why? The real bird is neglected. Simply outward covering. So similarly, I am spirit soul. That I forgot. Ahaṁ brahmāsmi: "I am Brahman." I am not this body, not this mind.
So people are trying to burnish the body and the mind. First of all they try to burnish the body. This is material civilization. Very nice clothing, very nice food, very nice apartment, very nice car or very nice sense enjoyment—everything is very nice. But that is to this body. And when one is frustrated to this very nice arrangement, then he goes to the mind: poetry, mental speculation, LSD, marijuana, drinking and so many things. These are all mental.
Actually, happiness is not there in the body, nor in the mind. Real happiness is in the spirit. Therefore Bhagavad-gītā says, sukham ātyantikaṁ yat tad atīndriya-grāhyam (BG 6.21). The real, the ultimate happiness is that which is beyond this material sense. Ātyantikaṁ yat tad atīndriya. Atīndriya means—indriya means the senses—transcendental to the senses. That means that spiritual. There are many instruction and practical also.
So unless we go to the spiritual platform, we cannot have actual happiness. That is the instruction Prahlāda Mahārāja is giving, that sukham aindriyakaṁ daityā deha-yogena dehinām (SB 7.6.3). The happiness perceived by contact of senses or contact of body, sukham aindriyakam . . . our present appreciation of happiness is due to the senses, and these particular senses are according to the particular body. Deha-yogena dehinām.
The other day we have explained that a hog, because he has got a particular type of body, his sense gratification is to eat stool. His body is so made that he will feel happy by eating stool. Similarly, another man, his body is so made that he will be happy to have kṛṣṇa-prasāda. So that we can make by Kṛṣṇa consciousness . . .
(break) . . . change the habit of the body. That is possible. How it is possible? By knowledge. The hog cannot be educated. His body is so condemned that it is not possible to educate the hog or the dog or the cat or the animal. Here is a body, by education one can become from doggish habit to goddish habit. That is possible.
So we have to take advantage. That is explained in the first verse by . . . Durlabhaṁ mānuṣaṁ janma tad apy adhruvam arthadam (SB 7.6.1): "This human form of body, it is very rarely obtained. It is not to be misused." That is the first knowledge. But people are not educated in that way. They are encouraged that go on, sense enjoyment, "Enjoy, enjoy, enjoy." Some rascal comes, so he also says, "All right, go on. Enjoy. Simply meditate for fifteen minutes."
But actually, this body is not meant for aggravating sense enjoyment. We require sense enjoyment, because that is a demand of the body. If we want to keep body in healthy condition, then the demands of the body—eating, sleeping, mating and defending—must be provided. But it should not be aggravated. Therefore in the human form of life, tapasya. Tapasya means austerity, penance, vow.
These are the teachings of all scriptures. Either you take Hindu scripture or Christian scripture or Muhammadan scripture, in every scripture human form of life is meant for training.
