Greetings Jewel!
Feng Shui is old knowledge and wisdom, and thousands of years ago there where no problems with Electro Magnetic Fields. Now they are around us all the time and they affect us whether we want or not. Feng Shui is about taking action so you can get energy from your surroundings and not vice versa and that your home will be a positive place to live. I'd say Memon is a perfect way to complete a good Feng Shui for our times. I have Feng Shui'd my house, updating every month, but still living in my house I would loose much of my energy. These frequecies disturb mind and body constantly. Having installed Memon in my house, my Feng Shui is completed. My home is more than ever a place where I gain energy. Marie Diamond also mentions Memon as being a part of the Feng Shui today. Memon too has been and is a treat every day as well as Diamond Feng Shui is. I recommend you check out the webpage that Shawn recommends.
Best wishes
