16 - H2 and Holistic Mathematics
As before we can define three sub-levels with respect to H2, concrete, formal and vision, though considerable overlap will now take place as between these levels.

The understanding that constitutes Holistic Mathematics for example is largely the product of the formal stage of H2. Though it is expressed in structural terms, it equally requires the corresponding spiritual state of this level for its proper comprehension.

However the key feature now is that direct vertical complementarity will take place as between the corresponding sub-levels of H2 and L2. This will of be Type 2 complementarity where "real" structures and - relatively -  "imaginary" states (or alternatively "real" states and relatively - "imaginary" structures) interact.
