Jiddu Krishnamurti (May 11, 1895 – February 17, 1986)
Indian born speaker and writer on philosophical and spiritual subjects

The division in our lives is the structure of thought, which is the action of the observer who thinks himself separate. He further thinks of himself as the thinker, as something different from his thought. But there can be no thought without the thinker and no thinker without the thought. So the two are really one. He is also the experiencer and, again, he separates himself from the thing he experiences. The observer, the thinker, the experiencer, are not different from the observed, the thought, the experienced. This is not a verbal conclusion. If it is a conclusion then it is another thought which again makes the division between the conclusion and the action which is supposed to follow that conclusion. When the mind sees the reality of this, the division can no longer exist. This is the whole point of what we are saying. All conflict is this battle between the observer and the observed. This is the greatest thing to understand.
