An idea can turn to dust or magick depending on the talent that rubs against it.
Our magick is a part of us and it is dependent on our own innate abilities. We have to work to expand our knowledge and our gifts. We have to acknowledge that no one has the same natural ability levels and are all on different levels of effectiveness. You should know what the ability levels are for yourself and everyone who you enter the sacred circle with. You must know that you can enter in perfect love and perfect trust, so you must be able to trust in their abilities.
