The Witness is a huge step forward, and it is a necessary and important step in meditation, but it is not ultimate. When the Witness or the soul is finally undone, then the Witness dissolves into everything that is witnessed. The subject/object duality collapses and there is only pure nondual awareness, which is very simple, very obvious.
Ken WilberThe great and rare mystics of the past . . . were, in fact, ahead of their time, and are still ahead of ours. In other words, they most definitely are not figures of the past. They are figures of the future.
Ken WilberEach band or level, being a particular manifestation of the spectrum, is what it is only by virtue of the other bands. The color blue is no less beautiful because it exists along side the other colors of a rainbow, and "blueness" itself depends upon the existence of the other colors, for if there were no color but blue, we would never be able to see it.
