In the book, The Doomed Aryan Race, regarding the symbol of the caduceus, Samael Aun Weor wrote:
"We know that the shape of the spinal medulla is very special. If we observe the sign of the infinite (the holy eight placed horizontally) we then see two parts that are reunited in the center.
Let us suppose beloved reader that you gather many horizontal eights and stack them up one on top of the other at their base then all of these horizontal eights will give you the shape of the spinal medulla.
Ancient wisdom teaches that there exists a pair of sympathetic nervous cords that in the form of a holy eight are entwined around the spinal medulla."
Why is the number 8/ infinite symbol referred to as holy by Samael?
