Edain McCoy in this book explains how magic works as the requirements to successful magic so it is quite interesting if you are learning about this topic.
The second chapter begins with some techniques to invoke and send power and some vizualization exercises as well very easy to execute I assure you. Then from the third chapter on Edain teaches how to choose the best moment to create spells which is very important to be successful and she gives a few examples. Well I guess you already have an ideia of the contents so I hope you read "Making Magick" soon and enjoy it.
