"The peak experience might be likened to a spot on a mountain top from which the surrounding panorama may be viewed; yet being on the top of the mountain does not supply more than the possibility of seeing, whereas this process of observation is different from that of mountain climbing[...]insight is distinct from the mental state from which it originates, and constitutes the result of a creative act in which consciousness at a certain height is directed toward what lies below."
--Claudio Naranjo
There is no becoming, no revolution, no struggle, no path.
Already you are the monarch of your own skin.
