Mind control is a controversial topic. While you can get into ones mind, controlling it is another story.
Start with the Basics, they can be found through Google or another search engine, if they are difficult to find,
add 'magick, pagan, occult, wicca' ect to the search.
The basics are as follows:
Colors and their meanings
Moon Phases and their meanings
Days and their meanings
Hours and their meanings
Herbs and magick Tools (Stones, wands, altars, ect)
Astral Projection and the Planes of Existence
Charms and Chakras
Aswell as your signs and spiritual attachments, Zodiac and elements,
totems, ect. Which can depend on your birthdate, and others require spiritual
guidance through meditation or dreaming. Communication with your spririt guide(s)
can also help you on your experience.
To run down the basics, If you want to learn how to write, or properly cast spells
YOU NEED TO LEARN THESE. There is short cut to truely participating in this practice
without this essential knowledge. You study until you have these memorized, and you may
forget a few along the way. As long as you keep practicing, is as long as you will remember.
A mentor is there to guide you, however they will not hand feed you everything you need to know
They are your teacher, they are the frame, they explain what you cannot understand. HOWEVER
it is still a Personal experience, something you need to be grounded in, and well connected
with your subconcious, there are some things your mentor cannot give you.
