It is like the power of water, which when uncontrolled can wipe out cities. The same power of water when controlled in a man made dam, can make land productive apart from producing electricity. So we should control our minds and concentrate on what is righteous. It is said whatever the mind of man can conceive and believe it can achieve. We can make and unmake our outer conditions by our thoughts and feelings.
Thoughts arise from our mind.
They are the culmination of our inputs through our senses. By the unique gift we have to discriminate good from bad, we should prevent the destructive stimulus from getting into our system. And we should feed in the constructive forces to carry on our life in the right direction. We have ample life examples to illustrate from the history how people by sheer mind power, though they lacked the necessary money power and muscle power accomplished astounding feats. Abraham Lincoln, Thomas Alwa Edison, Gadhiji and Mother Teresa are some to mention a few.
