The existence of land and water, the land for the water and the water for the land, the attraction between the heavens and the earth - all demonstrate a universal harmony. The attraction of the sun and moon to each other, the cosmic order of the stars and the planets, all connected and related with each other, moving and working under a certain law; the regular rotation of the seasons; the night following the day, and the day in its turn giving place to the night; the dependence of one being on another; the distinctiveness, attraction and assimilation of the five elements - all prove the universal harmony.

The male and female, beast and bird, vegetable and rock - all classes of things and beings - are linked together and attracted to each other with a chord of harmony. If one being or thing, however apparently useless, were missing in this universe of endless variety, it would be as it were a note missing in a song.

As Sa'adi says: "Every being is born for a certain purpose, and the light of that purpose is kindled within his soul."

All famines, plagues and disasters such as storms, floods, volcanic eruptions, wars and revolutions, however bad they appear to man, are in reality for the adjustment of this universal harmony.

There is a story told in India how once all the inhabitants of a village which had suffered from drought gathered together before the temple of their God, praying that for this year an abundance of rain might fall. A voice from the unseen replied: "Whatever We do is for the betterment of Our purpose. Ye have no right to interfere with Our work, Oh ye men!" But they again cried for mercy, and continued to do so more persistently. Then came the answer saying: "Your prayers, fastings and sacrifices have induced Us to grant for this one year as much rain as ye desire." They all returned home rejoicing. In the autumn they worked vigorously on their farms, and after having prepared the ground and sown the seed they prayed for rain. When they considered that sufficient had fallen they again had recourse to prayer, and the rain ceased. In this way an ideal crop of corn was produced and all the inhabitants of that country made merry over it.

This year more crop was grown than ever before. After the crops were gathered in however, all those who ate the corn died and many were the victims. In perplexity they again sought the God bowing low before the temple, crying: "Why hast Thou shown such wrath to us, after having shown so great a mercy?" The God replied: "It was not Our wrath, but your folly for interfering with Our work. We sometimes send a drought, and at other times a flood, so that a portion of your crops may be destroyed. But We have Our reasons for so doing, for in this way all that is poisonous and undesirable in them is also destroyed, leaving only what is beneficial for the preservation of your life."

The villagers prostrated themselves in humble prayer, saying: "We shall never again try to control the affairs of the universe. Thou art the Creator, and Thou art the Controller. We are Thine innocent children, and Thou alone knowest what is best for us." The Creator knows how to control His world, what to bring forth, and what to destroy.
