"One of the secrets of real magic is that it is controlled by the mind. The more things in your ritual to help your mind associate with your goal, the more powerful your ritual may be." - Scott Cunningham, renowned pagan/wiccan author.

They are ways to remind you on a constant basis what your goals are in life and how your mentality and positive thinking can help bring those desires into your life.
