The most striking feature of the perennial philosophy/psychology is that it presents being and consciousness as a hierarchy of dimensional levels, moving from the lowest, densest, and most fragmentary realms to the highest, subtlest, and most unitary ones.
Ken WilberYou can indeed be aware of your body, but you can also be aware of your mind - you can right now notice all the thoughts and ideas and images floating in front of the mind's inward eye. You can, in other words, experience your mind, be aware of your mind. And it's very important to experience your mind directly, cleanly, intensely, because only by bringing awareness to the mind can you begin to transcend the mind and be free of its limitations.
Ken WilberIn other words, all of my books are lies. They are simply maps of a territory, shadows of a reality, gray symbols dragging their bellies across the dead page, suffocated signs full of muffled sound and faded glory, signifying absolutely nothing. And it is the nothing, the Mystery, the Emptiness alone that needs to be realized: not known but felt, not thought but breathed, not an object but an atmosphere, not a lesson but a life.
