I did not expect this diagram to show here when i typed "the philosophers stone".
It is good that someone put the real thing for once too bad that it is not correct the square must be before the triangle.
For people wondering, this figure is Michael Maier's design, a Rosicrucian Alchemist. When I first heard about it, I thought that this is way beyond me, but when I looked closely, i was shocked. It's been staring me in the face all along.
It is a complete structure of the cosmos and its forces; it explains the whole of alchemy. The first circle represents the "Above", the perfect shape containing every other shape inside it. Most exalted and purified state of existence, or maybe even the Quintessence, that is created from the two opposites. as Michael Maier said "From a man and a woman, make a circle, then a square, then a triangle, finally a circle, and you will obtain the philosophers stone"
I do not think i am going to explain the rest of the shapes because it is going to take forever
