Light to Darkness

So much has happened. But what has happened has past. You may remember it but you must not indulge in remembering. To indulge in the remembering is to live by it. From the light to darkness is the way to hardship. From happiness to depression is the back and forth of us all. You may sometimes be in between the feelings. From light to darkness has many meanings to many people. But, each meaning is different to each person. Some may be alike but never the same. For each person is different. So now I must ask what does it mean to you?
