Human emotions and physiognomy.
Physiognomic image and hexagram Yih-King 23.

-

Lineaments of a face and perception of a time.
Eyebrows: ideas are in the future / infinite chronology of subjective human comprehensions.
Eyes: aspirations are in the present / relative chronology of subjective human achievements.
Mouth: events are in the present / relative chronology of subjective human actions.

Person thinks of the future but events endure at present time.

Analytical formulas of the canon of changes.
1 (eyebrows) affirmative thinking is (mouth) indisputable evidence of (eyes) absolute existence.
2 (eyebrows) doubtless reminiscences are (eyes) actual displays of (mouth) authentic past.
3 (mouth) objective assumptions are (eyebrows) intentional projections of (eyes) obvious future.

Potential energy is comparable with open and quiet emotions of a human face. Because if energy does not cooperate with other world categories there is no transformation of a power pressure to physical parameters of other world categories, that corresponds to quiet facial emotions. And if energy has maximal and absolute sizes then as a result of interaction with other world categories there is no reduction of power pressure, that is comparable with open emotions of a face.
