To answer all the questions we have put, we must put yet a further question: what is the thinker? Is the thinker separate from thought? Is the experiencer different from the thing he experiences? Is the observer different from the thing he observes? If the observer is different from the thing he observes, then there will always be division, separation, and therefore conflict. To go beyond this cleavage we must understand what the observer is. Obviously he makes this division. You who are observing make this division, whether it be between you and your wife, or the tree, or anything else. Now what is this observer, or thinker, or experiencer?
