THERE IS NO THINKER, ONLY THOUGHT.
"The observer is the observed" means that although in the true observation of Unitary Perception there may still be the META Process of thought, its superproduct, the illusion called "observer" or "thinker" is gone.
In the same way, the intense observation of UP is also free of the illusion of absolute time. In UP time is irrelevant.
The absence of the illusions of duality into the "subject" and "object" and time in observation is a great relief from stress and any psychological perturbation.
