Let nothing disturb thee,
nothing affright thee;
All things are passing;
God never changeth;
Patient endurance
Attaineth to all things;
Who God possesseth,
In nothing is wanting;
Alone God sufficeth.
~ St. Teresa's Breviary
The Witness is that which is capable of observing the flow of what is—without interfering with it, commenting on it, or in any way manipulating it. The Witness simply observes the stream of events both inside and outside the mind-body in a creatively detached fashion, since, in fact, the Witness is not exclusively identified with either. In other words, when you realize that your mind and your body can be perceived objectively, you spontaneously realize that they cannot constitute a real subjective self. As Huang Po put it, "Let me remind you, the perceived cannot perceive."
