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. Tapo divyam.
