The mutation is the law of Nature. And in keeping with this law of change, the seasons come in and go out in a cyclic order. In winter we feel a cold sensation. Trees shed their leaves, stand out sharply against the sky, and put a bleak look. Fields look desolate. The sky wears a mournful grey veil. But the laws of Nature decree that winter cannot rule eternally. After the cold spell of winter, spring appears and everybody welcomes it. The day is sunny and the refreshing spring wind begins to blow. Flowers bloom and the air gets laden with soothing fragrance. The cyclic pattern of Nature is reflected in life as well. Suffering and misfortune may come into one’s life for some time, and envelop one’s entire existence with drooping despair. But they must inevitably disappear and give way to hope and happiness as the fog disappears before the sun. If someone is able to show fortitude to face the difficulties, he will overcome it. If he can save his vision from being blurred by the mist or cloud, he can perceive a silver lining behind the dark clouds and hopefully wait for the clouds to vanish from the sky. So it is said—even in darkness light dawns for those who believe.
