Awareness is the current knowledge of events occurring within our scope of sensation and thought. One’s scope of sensation includes what he experiences through one or more of his five senses, i.e., sight, hearing, touch, taste and smell and what he experiences through his mental feelings. One’s scope of thought includes that which he experiences in his mind, such as concepts and images. Awareness consists of focus (concentration), perception, and thought. Awareness can be described as similar to concentric circles with the focus in the middle. There are things going on in the outermost circles of which we are least aware. At the center of the circles is the subject upon which we are concentrating.
