In plain words
They are passing. Why should we go through so much trouble for these passing pleasures? Three travellers set out for Bangalore. One took a first-class ticket. Another took second class. The third took a third-class ticket. The one with the third-class ticket suffers a little before he reaches Bangalore. The one who took second class suffers a little less than that; the one who took first class sleeps soundly in good comfort; yet all three get down at the same station. In the same way these scientists are providing physical comforts. But these passing pleasures give a passing joy. We enjoy passing pleasures, but we are moving away from peace. As much pleasure as passing comforts give, so much trouble they give too. What are we doing? Where are we going? We are making nuclear bombs, hydrogen bombs, atom bombs.
This moon gives coolness to the body, but it does not give coolness to the brain. All day long the brain stays heated. There is fear: when will the oxygen fail, when will the hydrogen fail? We sit in an air-conditioned room. The body cools down. The brain of one who has no peace grows hot. When his mind is at peace, a man rejoices even in a forest, calling it a picnic. So today science is taking us away from peace of mind. Today's scientist leads an artificial life. Ceaseless thinking, nothing but thinking. This mind has no rest.
The root cause of the diseases of people today is the lack of rest for the mind. Because of this, diseases are growing more and more. Whenever you look, it is thinking, thinking. Because of that the mind is spinning. We give rest only to the inert mind. But does the brain not need rest? The mind of one with too much intelligence is a devil's workshop. So it has been said; what peace can this devil's workshop have? Peace for the person, peace for society, peace for the nation will not come to us by any path other than the spiritual one. Recognising this principle well, we must strive for peace of mind and not fight for physical pleasures. Physical pleasures should be there to some extent, but they must be natural pleasures.
