Hello, beverlymayer! Welcome to the site! I hope you have a fab time here, and I wish you the best in your study, research, practice and spiritual growth!
If you make your way over to the articles section of the site, and you locate an article called the "SoM Survival Guide", you can find in there what we call "The Basics", just simply scroll down until you find it.
There are hundreds of books out there now of days on the subject of witchcraft and the beliefs that surround magickal practices. I encourage you to find some at your local bookstore or online. :)
