Everything in the Universe is energy. Everything. That includes all people, animals, trees, rocks - everything. Anything we consider "solid", such as the rock mentioned above, is simply energy that is compacted. If you take a microscope and look smaller and smaller, ultimately, you will find that even a rock moves with an energetic wavelength.
Now, building on that thought, all energy is neutral. It is not good or bad, hot or cold, left or right. But energy does attract like energy. (Stay with me now.) Our thoughts take neutral energy and give it a vibrational charge based upon what that thought is. The more attention we give to that thought, the greater the size. Additionally, that vibration (or energy) will attract like vibration making it even larger. Ultimately, that vibration will reach a level where that thought becomes real. Phrased another way, what you give your attention to will come into your reality. This is the Law of Attraction.
If you want a new pair of shoes, think and dream about the perfect pair, when enough energy has accumulated, the shoes will come into your life. Now, don't get to excited - or too skeptical - because there are many factors to be considered. The money to pay for the shoes might not be there if you didn't consider that in your thoughts. Also, if you have thoughts that say "Oh, this won't really happen" or "I'm not worthy or don't deserve another pair of shoes", then that thought creates a vibration of "No Shoes". So what shows up - shoes or no shoes - depends on where you spent the most energy. That is what happens to most of us. We ask for something from the Universe, but then effectively change our minds by having a conflicting thought. The solution? Don't have the conflicting thought. Yes, I agree; easier said than done. But you can get there! Honest! You can. The Law of Attraction works. Always. You can count on it. But those steps are for another day. Love to you, always.
