Sorrow is a cleansing process which makes it possible for you to understand what happiness is. Without it, you would not see, you would not experience, joy. Sorrow is here to wash off of you and wash out of you all the things that you do not need. It should be your dear companion, showing you what is tensing you up inside and keeping you from taking a step forward. It should then pack your problem into a bag and leave with it. It will do that, if only you let it.
