LOOKING

Both philosopher Alan Watts and spiritual teacher Eckhart Tolle have remarked that when something is looked at, it changes. 

Watts used the example of a thing being viewed through a microscope, as a result of which the thing is no longer the same.  Tolle says that a flower notices being noticed and changes.

Vedanta offers this explanation:  It is through all the eyes in the world that the Brahman sees itself.  The Brahman is both the observer and the observed.  When what is observed changes, it means that the Brahman has changed.
