Your mind is one of the most important tools you have when casting a spell. Without a clear mind and a focused mind, your intention will not be clear to the universe. To help settle down a mind that is filled with chatter or anxiety, it can help to practice visualization. Not only will this train your mind to be more effective at focusing, but it will also help you bring more energy to the spells you are working or the spells you are having cast for you. When your brain can clearly see the outcome, the spell will work even more effectively.
