This happened a very long time ago when everything was forming up and the universe was just beginning. Back then the Planets, the Stars, the Trees, the Rains, the Clouds and all the natural beings too, were young and used to go to school. They wanted to acquire learning just like me and you, so that later on in life they could assume their respective roles with a desired sense of responsibility. Amongst the various classes, there was a very special class, a wonderfully adorable class of colours. The names of the classmates were Blue, Green, Red, Violet, Pink, Purple, Black and White and so on and so forth. All of them were funny, lovable, joyful and sometimes mischievous. But Black and White were extremely naughty and were always preoccupied with causing mayhem and indiscipline. This was the reason why almost always they got late for the class. Plain simple words of advice or rebuke were not having much effect on them. One morning it so happened that the clouds rained heavily and darkness prevailed all over. Everything became sad and gloomy. Mother Nature and all beings could not cheer up even when the sun shone again because the light was so less. The immediate solution available was to appeal to this wonderful and talented class of colours. The authorities’ wanted these upcoming learners to run up to the sky where the heavy hearted clouds were waiting. Delighted and honoured all the colours ran up leaving behind a resplendent trail. This scene was so spectacular that the world smiled again. But because Black and White were as usual preoccupied in creating nuisance, they were not present in the class and so could not become a part of the rainbow. Then they realized the importance of being disciplined. From that day on they became so responsible and conducted so excellently that they are now considered very significant.
