Personally I see magick is a natural energy that is all around us. Those who learn to, are able to utilise the energy around them, and ask for a magickal response to our request.
A good place to start is with lots of learning, there are lots of great posts on this website that are a massive help:
But books such as: Before you Casta Spell by Carl McColman are very good for beginners.
I hope this helps.
there is an excellent post on how to go about studying magic athttp://www.spellsofmagic.com/read_post.html?post=876458
I would also recommend the books:
Modern Magick by Donald Michael Kraig
Spells and How They Work by Janet and Stewart Farrar
The Veil's Edge by Willow Polson
