I am extremely sceptical of the whole business of Negative Green (-Gn) being something bad for you, that typically sits in the lower third of pyramids. Chaumery had a large copper rod pyramid placed over his bed and after his death de Belizal dowsed a strong -Gn "energy" there.All the books on the VC are in FRENCH! "Essai de RadiesthÃƒÂ©sie", Chaumery and de Belizal is the main one. IF you look at the site:
http://www.biogeometry.org and click on Site Map and then Books, you will find a list of books in French. Chaumery died of Vertical Negative Green poisoning so the second book is by de Belizal and Morel. The last book in the list by ENEL is significant because he lived in Egypt and in fact was Russian. Dr Ibrahim (see below) learned about Biogeometry from ENEL.
I've always been interested in the subconscious attributes of colour and felt affronted that even a virtual colour could be held to be dangerous. On investigation a Positive Green person has love of life, photosynthesis presumably being the symbolic associative link, while a -Gn person has fear of it. Positive Red is love of fire and there is a -Rd which appears to equate to an inflated fear of radiation of all sorts which is relatively rare.
Chaumery, dowsing says, suffered the -Gn syndrome anyway, in which the pyramid actually played no part. However, de Belizal publicized his finding and ever since, the bottom part of pyramids have been a bad place to be. But when I started tinkering with pyramids and cones to alter the physical nature of things (remember razor-blade sharpening ?) -Gn did not present itself even when I invited it to. I ended up regarding it as another variant of "psychic attack" where fear is built into the approach from Square One and under that definition, can't be eradicated.
The sceptic in me appreciates that getting rid of intrinsic danger in one's existential concepts doesn't have any proof or disproof attached to it. It's just a lot easier way to proceed and I apologise if it seems critical of other approaches.
