Cancer is basically a psychological disease; it is basically a disease of the mind, not a physical one. When the mind becomes very tense, so tense that it is intolerable, it starts affecting the body tissues. That’s why cancer exists only when civilization becomes very, very sophisticated. In primitive societies you cannot find cancer. People are not so sophisticated. The higher – by ‘higher’ I mean complicated – the more sophisticated, the more complex a society is, the more cancer will happen. […]
Cancer has to disappear. Cancer can exist only in a certain neurotic state of mind. If the mind relaxes, sooner or later the body will follow and will relax.
It is because of this fact that scientific investigation has not yet been able to find a cure for cancer.
It is almost impossible to find a cure for cancer – and the day they find a cure for cancer they will create even more dangerous diseases in the world – because the cure will mean repression. The day they can find strong enough drugs to repress cancer, then some other disease will erupt. That poison will start flowing through some other channel.
That’s how it has happened down the ages. Simple diseases were cured and difficult diseases came into being. You cure one disease, another disease comes in. And the second one is more complex than the first. The first was a natural reaction of the body, the second is an unnatural, abnormal reaction of the body. You repress the second and the third will come and the third will be even more difficult to tackle. And so on, so forth. Now cancer is at the top. If cancer is repressed then even more difficult diseases will erupt in the human body and the human mind.
