Hi Anupma, Life is like that. If you are always happy how will you know that what is happiness. You can feel the pleasure of being happy only when you have experienced the sorrow. It is like two sides of a coin. If you have never experienced hunger how would you have the feelings of a poor people who gets enjoyment of all life if he is able to fill his belly with the food. Kids of rich people always ask for tasty food items. They don't enjoy bread and dal. You keep your kids without food for a day, they will get all the enjoyment when they eat meal after the fast. That's why, life shows all of its color to each and every person. Nobody departs without experiencing every aspect of life.
