Hi!!
just clicking around looking at stuff and saw this thread.
My understanding of alchemy (vis Kybalion) is that it is the transmutation of the spirit foremost and transmutation of elements secondly (ie

hilosophers stone, etc.). By using higher Hermetic principals to affect lower ones we may transmutate emotions, life processes and (yes) material.
Hermetic principals:
all things are mental
all things vibrate
" " exhibit polarity
" " " rhythm
causation
gender
correspondence
