The good news is that you already DO manifest everything in your life. You always have. Since we all already create our own realities, what we do in the course is slow down the creative process and learn how this is done, in order to understand the principals behind and in so doing adjust things and create something different. The spiritual realm is the world of Causes. The manifest material world, that is so familiar to us through our senses, is the world of Effects.
Thought always precedes manifestation in the material world.
So, when the Higher Self overshadows your conscious mind, you become a master of manifesting because you work on the fluid spiritual level where creation first takes place. When I was a little girl, I often heard adults describing the world they worked in as tough, heartless and devoid of love. As I watched people go about their daily business, I saw them living the reality of these messages. My heart was very sad. It all seemed like such a waste.
