You accept these principles of life, no meat-eating, no intoxication, no illicit sex, and there will be no cancer. Those who are strictly on this line, they never suffer from cancer or any such disease. Now take for example me. I’ve come here in this country for the last eight years. How many times have I gone to the doctor? That one heart attack. That is serious, that is another thing. Otherwise, generally how many times have I gone? I don’t pay any bill of doctor.

So if we live a very hygienic life, regulated life, there is no question of cancer or any disease. The disease is created by violating nature’s law. One of the causes of cancer disease is this contraceptive method. You can make research on it. So they are on one side discovering contraceptive method, contraceptive chemicals, and on the other side researching for cancer disease. And they say also smoking is one of the causes. So why not give up smoking and illicit sex, contraceptive method?
