The enthusiasm from the Greek entheos means, God in you. The Divine Intelligence made us in his image, gave us the "mind of god". Thus the ability to create anything we want with our minds. Over history we have forgotten this. Enlightenment is a remembering that we have this mind and as such we can change anything we find disagreeable, our thinking thus our lives. A method for deliberately transforming ourselves into whatever type of person we wish to be, is first to decide specifically what particular belief you want to change and to hold these firmly in your consciousness. Second, proceed to develop the new belief by acting "as if", you actually believed it. And third, believe and repeatedly affirm that you are in the process of self-creating the belief you desire. Look for progress not perfection.It's a simple secret. Act as if you believe and in time the belief will take hold of you. The "as if" principle was first put forward by the philosopher William James. Any belief that is disruptive to human happiness and well-being (God's Will), any belief that fastens itself adversely onto our consciousness can be changed. But it takes a strong will.
Fix this fact firmly in your mind, and no matter how many dis-empowering beliefs you hold, remember that they can be changed. Don't ever make the assumption that because your father or mother held these beliefs that you must hold them to. You need only believe what you choose to believe. Once you've become enlightened to this fact, that beliefs can be changed, then comes the process of removal. One of the most effective ways to do this is through a 12-Step program.
