Fear comes from not living in the present. We look behind us at all the terrible things that have happened and are afraid to repeat them in the future. We look ahead of us and see all the terrible things that could possibly happen, whether or not they've happened before. But we very rarely just sit in the present.
The Buddhists have a saying: "What, in this moment, is lacking?" When we can stay in the present moment, we become appreciative of all that is around us. We experience life, not fear. What is lacking is in our minds. It doesn't exist. Fear is centered around that which is not in the present moment, that which doesn't exist.
When we infuse our imagination with fear, it is no longer imagination but hell, a hell of our own making. We dream up all sorts of possibilities of doom and failure and become frozen in our lives, frozein in our careers, frozen in the past and the future, never seeing what is, only what isn't. But when we free our imagination of the fears borne of our histories, it becomes a powerful tool for creation.
True imagination is a powerful way to connect to the wisdom inside us. Our imagination is that field of possibilities that is limitless. Our imagination is where our dreams lie and our hearts open. Our imagination is, ironically, what connects us to life itself. Living from our imagination opens the world to us. Living from our history dampens our spirit and disconnects us from life.
