Here is an excerpt from my book, The Silent Master: Awakening the Power Within:
Your mind is the environment in which your ideas, thoughts and emotions reside. As with any environment, the goal is to make it as clean and pure as possible. I often find that people treat their cars better than their mind and body. Their car at least gets regular tune ups, good gas, careful washing and cleaning. But the quality of their minds their thoughts and feelings don’t get any attention at all!
