The root of all magic is intention. But what exactly is meant by magical intent? To elaborate: intention is the decision you consciously make to attribute meaning/purpose to an action. As you work the magic you hold the choice in your mind that these actions have this meaning and cause the movement of magical forces toward your goal. Each step of the process is like a microcosm of this principle. With the meaning of each action performed as a magical act held in the mind while its being performed. As an example: you decide that by drawing a pentagram in the air and visualizing it as a fiery glowing green, a protective ward is cast. As you actually go about drawing the pentagram, you hold this decision in your mind until the task is done.
