@vajrasattva,
Ha, Recon invented the trinity?!
p-bar, e-bar, n(e-bar)
id, ego, super-ego
thesis, antithesis, synthesis
pathos, logos, ethos
moon, earth, sun
+, -, i
Was there a subject matter I missed in that long list of threes?
Oh yeah, the triangle is the elementary shape and so the basis for geometry.
