-Magic is being able to detect and create change.
-Magick is aligning yourself with divine universal power, and thus influencing your reality. It is not an attempt to control everything.
-Magick is being a partner in the ongoing creation of your life.
-Magick is to take command of your thoughts, and set them to work in positive ways. To consciously align yourself with the creative power of the universe.
-Magick is to make choices in your life and take action - magickal and mundane - to manifest them.
-Magick is to release your intentions into the Divine, trusting that when it is right for you, it will come - and whatever does or doesn’t come, you accept it as a gift and strive to learn what you can from it.
