The stem of the Reality Funnel summarizes the alternation of the less conscious standpoints "perspectively". But if they don't only jump around there, they also have a closer effect on each other and are wound in places to cores which connect many perspectives harmoniously. (Without harmony they would fall apart again.)
Such a comparatively harmonious core as, for example, our inner self can hold our Awareness (I) together, and from it probably emanate more comprehensively harmonizing impulses for thought and action than from the adjusting roles of our little ego. On the other hand, this ego can often handle everyday situations better. Therefore, it is best that both devote themselves to their own subject and benefit only from the skill of the other. We can feel such a harmony like a beautiful concert. If, instead, the ego is once completely in line with the inner self, we can speak of unity, but hardly of harmony: The connection is too rigid and the duet probably short.
