The Cube
On my downloads page I placed a video that shows the dissection of the Cube in a Tetrahedron and four piramids. This dissection itself is known and described, for example, in Elisabeth Haich’s book “Initiation” (Einweihung, 1960). An introduction to the text I will place on this website on a modern version of Plato’s Elements.

The article in Dutch “De dans van Mercurius en Venus om de Zon” posted on my FB page in December 2016 can be found here.
Lao Tzu
Starting the blog on my new website the mental legacy of the great Chinese philosopher Lao Tzu inspires me:
Do the difficult things while they are easy and do the great things while they are small.
A journey of a thousand miles must begin with a single step.
Also the “Wei wu wei” principle:
Act without doing; work without effort
The result of my first single step of a new journey.
