Ups And Downs

In my childhood I used to wonder, why earth is not a single expanse of plain land with all the greenery, trees, shrubs that bore fragrant colourful blossoms tasty fruits and nuts and flowers full of sweetest nectar. My mother explained to me: "it is like our life, this moment you are happy, the next, you may be not. So there are hills, valleys, troughs and big deep turbulent oceans and mighty mountains immobile." I did not understand what she said then, nor do I claim to know now. But, looking back I think, my life has explained it to me.
