Fourth Dimension – Sacred Geometry, Alchemy and Mathematics – Rudolf Steiner
Steiner leads us to the brink of this new perspective – as nearly as it can be done with words, diagrams, analogies and examples of many kinds.

An Introduction to Modern Geometry
It is the living movement of water that makes life on Earth possible.

This pioneering classic on water is more relevant now than ever before.
