It is always very difficult to look at our own perceptions, because we cannot get outside ourselves.

Using the principles of 'water logic' we can, however, construct a map of our perceptions. We can then identify the central points into which other things feed. We can identify the repeating loops. We can see what points are peripheral - even if they had seemed central before.

We construct a 'flowscape' and then examine it.
