In your life do your best to be the best person you can and live by the principles in this book but you must let go of the outcomes. Think to yourself that things are as they are and life is as it is which is not always how you want it to be. Letting go is letting be. Roll with the punches, and go with the flow.
Alternatively if your mind becomes accustomed to dwelling solely on the pain and wounding that events or people can inflict, you can reach a point where everything, however trivial, annoys you. Eventually everything that happens will assume a hostile status in your mind and you will be constantly bemoaning your luck to others around you.
Let other people around you be who they are and settle into the relationships with them on this basis. Others around you are not perfect but then neither are you. Making demands on others around you that they must behave in the way you think is right can destroy relationships. It is particularly important that you practice letting be in your relationships with your friends and family. You cannot control other people and after gently trying to influence them, if you are unable to let go and let be, you are surely in for an unhappy life.
From time to time in life, unless you are very lucky, you will have to face seriously challenging events and situations. How we cope with tragedy, disaster and bereavement depends a great deal on our attitude. Suffering can be intense without destroying our outlook on life. Once we have acquired inner peace and serenity it is easier to maintain our fortitude, and recover our strength quicker when confronted by difficult external circumstances. If we allow ourselves be overwhelmed and paralysed by our personal problems, however tragic, we only increase our difficulties and become a burden on those around us. In time you will start to live again. Accepting tragedy involves giving up old plans and dreams, and not spending the remainder of your life mourning what might have been. In time you can begin living a new life- albeit a life forever changed by the tragic event, believing that there is always a life worth having and living, and that despite tragedy, life does indeed go on.
