If a shoe has minor problems, it can be rectified and reused. However if it has major problems, you need to throw it away and replace with a new shoe. This can be applicable to the employee/husband/wife and so on.
There was once a holy man who used to sit under a tree, meditating all the time. He was so still, while he was meditating, that doves used to sit on his shoulders. One day some children came by and asked whether he could catch a dove for them.
The next day, the holy man closed his eyes with his mind set on silently catching the bird. The doves did not go anywhere near him. Do you know why? It is because his mind was not in harmony with when he wanted to catch the dove, and the doves understood that his mind was not in harmony.
When you have no hatred, no enmity, then you will have cultivated a sound mind which will be in harmony. Your mind will not only be calm then, but very strong. If you know how to harness the capabilities of the mind, it is possible to work wonders with its immense power.
