The key to living a happy and fulfilling life is to trust in our higher self. The body is neutral; if just follows its biological urges.  The mind or ego does all the evaluation and judging and that is where the confusion and pain comes in.  The higher self is who we are beyond mind and body.  This part of our self has to be discovered and nurtured.  It is the key to living a life of peace and joy regardless of the pains of the body and the anxieties of the mind.
