The great monk Swami Vivekananda had explained the secret and power of work in his complete work. In a chapter on work, he had written the following lines.
No one can get anything until he earns it.this is an eternal law. We may sometimes think it is not so,but in the long run we become convinced of it. A man may struggle all his life for riches; he may cheat thousands ,but he finds at last that he does not deserve to become rich, and his life become a trouble and nuisance to him. We may go on accumulating things for our physical enjoyment, but only what we earn is really ours. A fool may buy all the books in the world, and they will be in his library; but he will be able to read only those which he deserves to; and this deserving is produced by work.
Our work determines what we deserve and what we can assimilate. We are responsible for what we are; and whatever we wish ourselves to be, we have the power to make ourselves.
What we are now is the result of our past actions, it certainly follows that whatever we wish to be in future can be produced by our present actions.
You must remember that all work is simply to bring out the power of the mind which is already there, to wake up the soul. The power is inside every man, so is knowing; the different works are like blows to bring them out, to cause these giants to wake up.
