Here is an excerpt from my book, The Silent Master: Awakening the Power Within:
As you go about purifying your energy, it's important to recognize the positive qualities you already demonstrate. Split yourself in two for a moment, and list the positive and negative qualities you possess. Don't be surprised if you have to work hard at this, especially at acknowledging your good nature. In order to control and purify your energy, you have to know where you stand first! Since you may not be used to observing yourself, this will be a good practice to find out how to direct your efforts. Try it like this:
I make an effort to eat pure, balanced foods.
I get angry at slight provocation and usually cause a fight.
Practice identifying the attitudes and conditions that affect your energy. Events in your life are teachers and give you much feedback about what works and what doesn't. Think about your past and ask what specifically happened here or there that played a role in creating constructive changes for you. Think of a situation in which your energy changed in a significant way. What did you do to change your energy? What happened as a result? You can probably find instances where certain negative attitudes or actions created a negative result and instances where either consciously or by accident you took an action that worked positively for you."
