Dear Cecil: Some time ago I asked you how I could activate a mountain star, you said that amassive object( crystal or quartz) or a large painting or work of art should be placed on a shelf against a wall without a window.I did that in my bedroom as you said, now , my bedroom is over the main door ,Is that good?.Another question:How big should a door be?, Is there an appropriate measure?, Does it have to be a certain percentage of the total area? Thanks a lot for your answer
