A brief commentary thereupon:
Know what you are doing. Read the instructions and pay attention to the fine print. Practice your rites and rituals. Think before you spell.
Read about magic and the occult. Familiarize yourself with different systems of magic. Study religion, mythology, psychology, folklore. Acquaint yourself with the mystics. Read widely. Be informed about current events. Nourish yourself with the sciences, literature, and the arts.
Have a goal. Formulate a purpose. Know not just what you want, but why you use magic in the first place. Don’t just experiment; formulate a hypothesis and test it, but always have an overarching plan. Be determined. Make a commitment. Expect boredom and respond with discipline. Turn off the television, close the web browser, and put on your ritual robe at the appointed time.
Expect to be scared occasionally. Expect to feel lonely. Don’t be surprised when you wonder if magic is Worth It. Expect to encounter stuff you don’t understand. Expect your internal shit to be stirred up and sometimes to come flying at you through the fan of magical activity. Accept and process your emotions. Take care of yourself emotionally and physically. Learn to find better ways of self-care than the old ones you inherited from your parents or parental figures. Get enough sleep, and pay attention to your dreams.
To Keep Silent
Keep a magical journal. Document carefully. Limit your time on the Internet. Keep your magical workings off of Facebook. Don’t talk about stuff so much that you lose all impetus to do it. In short, SHUT UP AND DO THE WORK.
