My point if view is (sorry, I've nothing to draw):
Consider the angle from the center of the chart rather than polygon angles.
The chart is divided in 12 parts (360 / 12 = 30); and not in 5 or else
Aspects are in relation with angles being a multiple of 30 (a plain sign) or the half of one of them
There are : 30, 60, 90, 120, 150, 180
Then :
210 is the mirror of 150
240 is the mirror of 120
270 is the mirror of 90
Else :
So there is no place for angles like 72 despite is = to 360 / 5.
I don' t know them all but the rule seems to be:
if they have a relation with the 1/3rd, 1/6th... and not with 1/4th, they are beneficial, soft class.
if they have a relation with the 1/4th... they are harmful, hard class.
conjunction is just without concession, and considered to be "hard" - (Venus conjunct Jupiter must not be so hard to live)
Personally, I think them in term of resonance VS dissonance rather than beneficial VS harmful.
Thank you for this.
But what about the phisical aspect of this?
I am at the center of the chart, I look at the sky, and there are 2 planets 135 degrees of distance from one another.
With me these form a triangle, which is 1/8 of an Octagon, with the angle of an Octagon.
These shapes and positions would generate a force field, and energy pattern, that define X quality of said aspect.
Even if it's not based on 30°, there is still a forcefield related with Pentagon at 108°, and 72°, yes?
