displays of human eyes and physical measurements of space

-

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 outside of time / irrelative chronology of subjective human actions.

Person understands that the future depends on the past, but it is impossible to change anything in the past time.

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

Energy can possess physical sizes which are equivalent to measurements of space, namely can exist multivariate energies possessing different power coordinates.
Time too can possess sizes or magnitudes which are connected with various measurements and coordinates of space.
Movement too can possess physical parameters or scales which reach in various spatial measurements and dimensions.
And also matter and life can have different measurements and coordinates.
