A quick overview with some correspondence to Tozan's five ranks and the path(s) as outlined by western mystics.
View is dualistic, and identity is exclusively with the human self. "I" am this human self.
- Detaching I
Detaching from dual view and exclusive identity with the human self.
Tozan's second rank. Dark night of the senses.
Deepening transdual view and identity as Big Mind/Heart and the absolute. "I" am the absolute.
Tozan's third rank. The brilliant sun of enlightenment.
- Detaching II
Detaching from habitual transdual view and exclusive identity as the absolute.
Tozan's fourth rank. Dark night of the soul. Fall from grace.
Deepening integration of the absolute and the relative, Big Mind/Heart and the human self. Increased fluidity. No exclusive or habitual identification. There is no fixed "I" anywhere.
Tozan's fifth rank. The hazy moon of enlightenment. Integrated free functioning human being. The unitive life.
The transitions from the two phases of detachment to the following ones may come to an end when we are ready to embrace the pain in it. When we can fully accept and melt into whatever we are experiencing.
In my experience, phase two was more of a sense of being pulled apart and put together again in a new way - with a good deal of awakenings and illumination mixed in. Phase four was one of being completely ground to dust - on a very human level, with a sense of a complete abandonment of the absolute and of being completely abandoned by God (Buddha Mind). During the early integration phase, the absolute returns although now in a way that seems completely ordinary and unremarkable.
Looking at it this way, the process makes a good deal of sense - although probably most often recognized only in hindsight.
First, there is an exclusive identification with the relative. Then, a detachment of this identification. This is followed by an exclusive identification with the absolute (and a sense of "I" having attained it), and later by a detachment of this identification. After this tour of the relative and the absolute, we are ready to integrate both in a more grounded and ordinary way.
Or even briefer:
- (a) Dual, (b) Detach I.
- (a) Nondual, (b) Detach II.
