ALCHEMY

Alchemy in her spiritual sense is a virtue of searching, part of growing up, in the last path of knowledge.   
In its day to day sense it’s the transformation of simple metals to fine metals,

and the conquest after the elixir which is the spice of life
The fundamental base is that all foundations- fire earth, water, air and atman- which is the inner soul,

all of the above in different combination create every materiel in this world.
