As we have seen, in basic terms, differentiation in development relates to the linear approach (1) in the discrete separation of opposite polarities in experience.
By contrast integration in development relates to the corresponding circular approach (0) in the continuous uniting of polarities through recognition of their complementary nature.
So the very processes of differentiation and integration, representing transformation with respect to development, can be fundamentally encoded in mathematical terms through the holistic binary system.
However it is only with the onset of Band 6 (with respect to my map) that mature specialisation with respect to both to the differentiated (linear) and integrated (circular) aspects can take place, This then enables, through the unfolding of the 3 Levels of Band 6, the smooth interaction of both the dual (phenomenal) and nondual (spiritual) aspects to take place in experience, that is both extremely creative and immensely productive.
Now I am conscious here of being capable of giving but an impoverished perspective on these most advanced stages. In my blog entries, I hope to be continue to clarify key features (based on personal experience) up to the onset of the 3rd level of Band 5. However as there is a valid sense in which on-going future levels are already implicit in what has already unfolded, one can, to a degree, project this development forward to see what might transpire later (though necessarily in a somewhat diminished sense).
Though I can therefore fill in the structures associated with Band 6 (and to a lesser extent Band 7) I cannot yet provide a precise account of the lived experience associated with these levels.
So with this warning in place we will now proceed!
Once again, though there is a certain discrete differentiated sense in which these new levels can be located with one particular band (i.e. Band 6), it is also very important to remember that a high level of two-way integration now attaches to these levels with all other major levels on the spectrum.
So from one perspective, the Levels of Band 6 represent the full fruition of the earlier Levels of Band 2. However these were initially experienced in a somewhat rigid manner (reflecting over-differentiation) which thereby significantly reduced dynamic access to the other Bands on the Spectrum, this situation is now rectified. So the dualistic differentiating capacity (early associated with Band 2) is now restored in an enhanced flexible manner, whereby it is made fully compatible with the need to integrate this level with all other levels.
Likewise from an equally valid perspective, the Levels of Band 6 represent the full fruition of the earlier Levels of Band 4. However whereas these were initially experienced in an unstable flexible manner (where nondual realisation was not properly grounded in the phenomenal world), this situation now likewise has been rectified, so that both dual and nondual aspects can mutually serve each other.
And as Band 4 had earlier represented the significant integration of the Bands 1 and Bands 3, we have now - literally - reached the stage at Band 6, where the Levels of earlier Bands can be given a certain distinct discrete (differentiated) identity, while equally being given a continuous (integral) identity through their relationships with all other Levels.
As I would see it (as an extension of my own particular perspective), the 1st of the 3 levels of Band 6 (which I customarily refer to as Radial Reality) would represent, from a scientific perspective, a refined intuitive vision logic type of understanding that would be highly creative (indeed truly visionary) in quality, but still lacking full grounding in phenomenal reality.
The second level would then be more formalised, reflecting the integrated use of linear reason with intuition, while the 3rd level would open up full access to concrete reality (now fully experienced in the light of a mature nondual awareness).
So in this way, the 3 levels of Band 6 would unfold in a reverse manner to the corresponding situation at Band 2.
As regards Band 7, I must of necessity be more speculative.
In some respects this represents on-going development with respect to Band 6. However I have suggested before that it is likely to be associated with a stronger emphasis on suffering involvement with the world.
From one perspective, this could well reflect the diminishments of age and a decline in physical (and perhaps mental) ability, associated with increasing health difficulties.
However, equally it is likely to reflect the final big surrender of personality in deliberately going against type.
Thus I have portrayed two principle types i.e. active and passive. Now the active are typically more likely to feel better able to engage with the dualistic world of everyday affairs.
The passive (who are inherently more contemplative) may however instinctively experience a natural reluctance for such involvement and even a strong distaste for much natural activity. I would see myself as belonging to this latter group.
So in the final stages, the active type may be required to go against type in adopting a more contemplative stance, whereas the passive type may equally feel required to go against type in becoming deeply committed to some active cause.
In neither case, will this late "conversion" come easily and is therefore likely to cause much suffering.
So Band 6 in my account is principally associated with the attainment of true wisdom (representing the now highly refined spiritualised cognitive function).
Band 7 is then principally associated with the attainment of true compassion (representing the corresponding refinement of the spiritualised affective function).
And of course the motivation which enables the ultimate harmony in the personality of these two complementary functions itself represents the full refinement of the spiritualised volitional function as the pure expression of divine love (expressed through the limitations of the human personality).
There is of course a small select group of highly talented individuals that belong to the "mixed" group (with strong inherent capacities for both dual and nondual experience).
However because of their special gifts (often associated with strong charisma of personality) greater demands and responsibilities are likely to be placed on such individuals, which again may culminate in a great deal of suffering later in life.
So in the end the final purpose of life is to learn to properly face death, which thereby represents the culmination of all psychological development.
