“The idea is like a blueprint, it creates an image of the form, which then magnetizes and guides the physical energy to flow into that form and eventually manifests it on the physical plane.” Shakti Gawain
Shakti has great wisdom, including about the law of attraction. Here she explains how the law actually works with physical objects. It all starts with an idea in our mind. If we believe that everything is an idea in the Mind of God, we will have smooth sailing. (This philosophy is called Idealism, and was developed in the Nineteenth Century by George Berkeley.)
Ideas do create form, and the better the idea is, the better the form. This means that we need to think carefully about what we wish to draw to ourselves. If we think haphazardly, we will draw that which is imperfect—not a way we want to go. If we develop our idea(s) with great care, we will see perfection in their manifestation.
Everything starts as an idea in the our mind, just as creation, I believe, started as an idea in the Mind of God.
Think well, and our life will become a picnic.
