Magical selling is the act of influencing people into action through non-physical means. But you must understand that magic does not entirely replace physical processes. Regardless of how much you are able to access and influence things from the higher dimension, you still live in the fabric of this reality. And you must abide by the rules of physicality it imposes. There are good sales techniques and sales practices known. Unless you use them, you will not be translating your magical work into this reality.

Truth is often a matter of the smallest degree. Science becomes better as knowledge of the universe becomes more precise. The smallest degree is the Quantum. It took Thomas Edison ten thousand attempts before he found the right formula for making a light bulb. The slightest variation would not work. He had to find the exact degree of truth in that formula before he could change the world. Magic is both a theoretical and experimental science. The better you perfect the formula the better you can change.
