Just like there is affection, attraction. This gentleman, my friend, who was begging from the doctor, "Doctor, another four years' duration of life." Why? He has got so much attachment. So once we are attached to this material way of life it is very difficult. It is very difficult. So brahmacārī is trained that this cosmic manifestation in which we are put by chance, this is temporary. Everything will be finished today or tomorrow or after a hundred years.
But just try to understand that you are eternal. Sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Na jāyate na mriyate kadācit (BG 2.20). You have no death, you have no birth. Your the birth and death is due to this body. That's all. Just like I told you, death means sleeping for seven months, again rise up. Suptotthito nyāya. Just like in the morning . . . while sleeping, you forget everything, but as soon as you get up from the bed you remember everything, "Oh, I have to do this, I have to go there, I have to do this." So many things you remember. Similarly, as soon as we get our again consciousness in next body, then our another batch of duty begins according to the body.
That is also explained, deha-yogena dehinām (SB 7.6.3). Another standard of sense gratification. Because the human body's sense gratification is different from dog's body's sense gratification. Or European sense gratification is different from African sense gratification, because it is due to the body. So wherever you take your birth, in this planet or another planet, or this family or that family, this nation or that, that sense gratification arrangement is already there according to your body. You cannot improve it. If a dog likes to gratify his senses like a man, it is not possible, because he has got a particular type of body. Deha-yogena dehinām.
So that sense . . . just like a dog has no economic problem. So a cat has no economic problems, a bird has no economic problem. But we civilized human being, we have got economic problem. Why? Now, because the advanced consciousness which are to be used for understanding our relationship with God, we are utilizing, misusing it for sense gratification. The advanced consciousness which was given to us by the law of nature, to utilize it to understand what is God, what is my relationship with Him and what is my duty in that relationship, this is the boon to understand in the human life, but we don't care for it.
