Geometry effects the flow of energy/sound/light/etc in and around it. This also applies with your body geometry (yogasana, or yoga poses) which is your pic 1. An inner implication of the geometry though is, when you visualize shapes they do the same thing. This is because your brain is a very strong electric transmitter and our natural EM field extends from the body interacting with the broader world. Some shapes, like platonic solids or especially base sacred geometry, like pic related, intrinsically effect the universe, gross and subtle. Namely the 5 platonic solids are the 5 elements.
>Earth, physical form and concrete structures
>Water, emotions and liquids
>Air, mind and gases, particularly O2 in biochem
>Fire, passion/desire, and electricity & plasmas
>Aether/Akasha (Quintessence), Space, Void, wisdom & pure unconditioned presence
The runes are similar nature though admittedly 2d instead of 3d. If you can't see or find the utility then you need to study deeper (not just this topic but your chosen topics as well) and you will see the disciplines and how they seem to converge around certain proportions and mathematical relations. Then after, you will start to have 'quantum tunnel epiphanies' in which your insight bridges to another study you had presumed merely unrelated, however they both still exist in the same universe.
