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 WilberIn the stillness of the night, the Goddess whispers. In the brightness of the day, dear God roars. Life pulses, mind imagines, emotions wave, thoughts wander. What are all these but the endless movements of One Taste, forever at play with its own gestures, whispering quietly to all who would listen: is this not yourself? When the thunder roars, do you not hear your Self? When the lightning cracks, do you not see your Self? When clouds float quietly across the sky, is this not your own limitless Being, waving back at you?
Ken WilberIf humanity doesn't destroy the planet first, which is always a possibility because as Spirit threw itself out there, that included free will. So, if we don't blow ourselves up first, soul will become as common of a mature development in adults as mind currently is and, eventually, Spirit will become the common experience for humanity.
Ken WilberGreat art suspends the reverted eye, the lamented past, the anticipated future: we enter with it into the timeless present; we are with God today, perfect in our manner and mode, open to the riches and the glories of a realm that time forgot, but that great art reminds us of: not by its content, but by what it does in us: suspends the desire to be elsewhere. And thus it undoes the agitated grasping in the heart of the suffering self, and releases us - maybe for a second, maybe for a minute, maybe for all eternity - releases us from the coil of ourselves.
