Human emotions and physiognomy.
Physiognomic image and hexagram Yih-King 22.

energy corresponds to joyful emotions of a human face

-

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 past / inevitably final chronology of subjective human achievements.
Mouth: events are in the past / inevitably final chronology of subjective human actions.

Person thinks of the future but events remain in the past time and do not exist in the future.

Analytical formulas of the canon of changes.
1 (eyebrows) affirmative thinking is (mouth) uncorroborated evidence of (eyes) unconvinced existence.
2
(eyebrows) doubtless reminiscences are (eyes) disappearing displays of (mouth) denied past.
3
(mouth) negative assumptions are (eyebrows) intentional projections of (eyes) irrelevant future.

Energy possesses kinetic and potential properties.
Kinetic energy is comparable to joyful and sad emotions of a face. Because as a result of reduction in sizes of power pressure there is transformation of energy to physical parameters of movement or other world categories, that corresponds to joyful facial emotions. And as a result of reduction of movement or transformation of a matter into energy there is generation or otherwise to tell increase in sizes of power pressure, that corresponds to sad emotional expressions of a human face.
