When the deepest part of you becomes engaged in what you are doing, when your activities and actions become gratifying and purposeful, when what you do serves both yourself and others, when you do not tire within but seek the sweet satisfaction of your life and your work, you are doing what you were meant to be doing.
Gary ZukavIf your thoughts are thoughts that draw low-frequency energy current to you, your physical and emotional attitudes will deteriorate, and emotional or physical disease will follow, whereas thoughts that draw high-frequency energy current to you create physical and emotional health.
