OK, I need some thoughts here. Other than suggesting that I have to be committed to an institution. So here go the facts: My wife claims that she's not sleeping well. Then she gets a book on Feng-Shui, goes through the room with a down to earth compass, and realizes -and I swear I've seen it-, the magnetic north actually shifts West on her side of the bed; furthermore, this is very much noticeable sweeping the compass through the room and bed. Perfect repeatability every time we pass the thing over the room and bed. Anyway, I did not give much of a thought since this is all too normal in any house due to piping, vent ducts, walls, you call it, and I filed the whole thing in the "so what / what do I care" box of thoughts. So I go for travel, and when I'm back she shows me -with a big smile- the compass through the room and the bed. North is North now all over the place. The needle cannot be steadier. And all the piping, ducts and nails are in the same place too. I ask, "what did you do?" (And here comes the part where everyone tells me "Aw com' on!") -She answers, I've placed a "Mandala" under the bed, which corrected the energy unbalance, and gives me some sort of explanation about energies that, as an engineer, I'd find laughable -this to use the kindest words that won't get me ostracized for a month-. Except for the fact that the bloody compass points the right direction all over the place, and before did not. Please, any one tell me that it is possible to remove all metal in a house in less than a week and not to leave a single trace of the construction work, or that compasses change their pointing with temperature, humidity, or solar spots. Or perhaps she installed an NMR machine in the basement that I did not see? Can anyone give me a rational explanation of this? I find hard to believe that a painting will change geomagnetism.
