The Fourth Dimension

Uneven numbers are masculine, even numbers feminine: “The uneven numbers of Christian dogma [‘the Trinity is decidedly a masculine deity’] are interpolated between the even numbers [in the axiom of Maria] which signify the female principle, earth, the regions under the earth..” C.G. Jung, Psychology and Alchemy 

‘..we come to one of the central axioms of alchemy, namely, the saying of Maria Prophetissa: “One becomes two, two becomes three, and out of the third comes the one as the fourth.”’
