The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift.
Manifesting is about being attached only to thoughts you wish to create. It is about embracing and presenting the very image of all that you wish to become ... first in energy form ... and then allowing that to bloom. You resonate your view. Momentary fantasies or mind trips are not going to draw it in. But focused thought draws whatever you want into your experience.
When you obsess - you are actually creating. Good, bad, or indifferent. As you shift your thoughts, your energy shifts to vibrate that image, presentation or awareness. Example: a person who is confident vs. one who is insecure. The body language and image reflects the energetic state. So it goes with other states of being and awareness. Learning how to, not only project what you want to portray, but to become that complete package is what manifesting is all about. And the only way you can get good at it: Practice.
