The life of this world is for the purpose of putting man to the test. Therefore, here man has been given complete freedom and all sorts of opportunities. Apparently, a man is free to do whatever he likes and to shape his own future in whatever way he likes. But in the midst of these preoccupations, certain events unfold which teach lessons to thoughtful persons and which indicate the fact that all this is temporary and will very soon be taken away from them. One such example is that of green vegetation on the earth. When there is rain, the earth becomes lush green with different kinds of vegetation. Man is pleased with this; he starts thinking that things are completely under his control and very soon he will be the owner of a rich crop. Exactly at the same time, some calamity suddenly befalls him, for example, a tornado strikes, there is snowfall or there is a plague of locusts and in this way the whole crop is destroyed in a moment. The same is true of man’s life. Man is born with a fine body. The worldly factors are in his favour and he shapes for himself a very successful and glorious life. Now he develops confidence in himself; he thinks that his affairs are under his control. But one day, or one night, he suddenly meets with death. A person who considers himself powerful, suddenly finds himself in a condition of total helplessness and powerlessness. If man keeps this reality in view, he will never be arrogant in this world; he will never be guilty of oppression or injustice.
