This is the seal of alchemy. It is actually a formula. The circle in the middle stands for the void (nothingness in a state of potential). the square around it represents thought…meaning that the thoughts activates the potential energy. The triangle represents intention (as added by universal energy or source mind) and the outer circle stands for manifestation. So it is basically a formula telling that thought creates reality… and the reason the inner and outer circle are the same shape, is because of the truth that everything-ness is nothingness. This symbol is from back in the day when it was a big secret that mind is actually what creates manifestation.

square the circle. love it
Jives well with "In the beginning there was the Word". Troublesome at the edges though since implies that divinity is within and free will is at best partial. ppl dont like that bit lol. Thoughts composed as words passed amongst community members creates the shared delusion of a universe we inhabit.
Interesting. Thanks for triggering muh brain to ponder. Careful with alchemy. Alchemist themselves sometimes the first transmutation.

I think your perception of my interpretation may be slightly off center - respectfully.
To simplify, It’s an encouragement to align to love, positive thoughts, have faith in the unseen.
My use of alchemy is spiritual and emotional; meaning I transmute (or change) negative energy with love. Negative words or opinions do not phase me; I know everyone speaks based on their own experiences, beliefs, societal beliefs they have formed, and project their inner being outward whether good or negative.
I don’t do some secret spell or potion. I speak love and healing towards others. I see beyond the surface and recognize projected negativities or fears are based upon pain or worry they carry in their heart. 💜
