Your magical power will be as effective as you are able to focus and control your mind. If you are distracted by many personal desires and interests, you will be weakening your capacity to be effective with magic. This sort of distraction may not be your fault entirely. You may have noticed a faint resistance to performing magic. This force is from your own invisible adversaries. They never stop trying to keep you weak. It is up to you to be vigilant in meditation and magical practice. At times this will be very difficult. One excellent way to handle this is to surround yourself with things that encourage you to keep up good habits which promote your abilities.
