The real position is, because we are spiritual, we should live in the spiritual world. At the present moment we have lost our spiritual constitutional position; therefore we are in this material world. Just like a man is generally healthy, but sometimes he falls sick, so at the present moment our condition is sick. It is called bhava-roga. Bhava-roga. Bhava means to become, and roga means disease. What is that bhava-roga? We are appearing, taking birth in the material world. This is called bhava: "You become." And after sometimes you become finished, means death. This is called disease. Bhava-roga. Yes. We have to cure this disease and come to our healthy standard of life. That opportunity is here in this human form of life. If you want to cure this material disease and revive your healthy condition of eternal spiritual life, the opportunity is here. Therefore our only business in this human form of life is to cure this material disease, not to aggravate it. Disease should be cured, not to increase it. But at the present moment we are mad after increasing the disease. We are acting in such a way that we have to accept another body. That means material disease will continue.
So to live irresponsibly like cats and dog is very risky life, because so long we shall be engaged in the matter of sense gratification—material life means sense gratification—we shall increase our prolongation of repetition of birth and death. So this irresponsible life of eating, sleeping, sex life and defense like cats and dog will not help us. Therefore . . . because this kind of activities will oblige me to accept another body. And as soon as we accept another material body we become subjected to the stringent laws of material nature. And the material miserable conditions are summarized into four items: birth, death, old age and disease. So those who are not in knowledge of the spirit soul, they are very irresponsibly prolonging his life in material activities.
