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.

There are several different meanings of the words "religion" and "spirituality," all of which are important. The whole point about an integral or comprehensive approach is that it must find a way to believably include all of those important meanings in a coherent whole.

Were you somebody different a thousand years ago? Will you be somebody different a thousand years from now? What is this One Self that is forever your own deepest being? Must you believe the lies of time? Must you swallow the insanity that One Spirit does not exist? Can you show me your Original Face, of which there is One and Only One in all the entire World?

So spirit is both the highest "level" in the holarchy, but it's also the paper on which the entire holarchy is written. It's the highest rung in the ladder, but it's also the wood out of which the entire ladder is made.

On my tombstone, I really hope that someday they will write: He was true but partial.

An integral approach acknowledges that all views have a degree of truth, but some views are more true than others, more developed, more evolved, more adequate.

If 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.
