Jung's conclusions on alchemy:

"We are dealing with life-processes which, on account of their numinous character,

have from time immemorial provided the strongest incentive to the formation of symbols.

These processes are steeped in mystery; they pose riddles with which the human mind will long wrestle for a solution, and perhaps in vain. For, in the last analysis,

it is exceedingly doubtful whether human reason is a suitable instrument for this purpose.

They are the primordial images."
