Regarding bed position? When I was a child I slept in a bed with a window right by me. I slept facing that window. In summer, the window was open with nothing but a screen between me and the night outside. I slept very well, and often had wonderful dreams about climbing out the window to go and play under the moon. In winter I liked to write on the frost on the window interior with my fingernail with my little arm braving the cold while the rest of me was cuddled under the quilts my granny had made. I was never afraid. I do not think I was harmed in any way by the window nor the energies from it, nor from my back being toward the door to my room. But that was long ago in a more peaceful era. And I had said my prayers sincerely before bed, so I was protected, I believe, in my life and in my dreams.
Lately, I was working on a little room newly constructed off the garage which would be a workroom, craftroom and garden shed for potting plants. I looked at feng shui again. There seems to be more nonsense than ever. Still, i found a site to tell me where my auspicious areas would be according to my gua. I read with interest until I was interrupted. When I came back to my computer, I had lost my place, so I looked up the personal number info again. Another site said that my number was not seven because i am female it is six. A whole new directional luck placement needed to be studied. So one expert said 7, another said 6.
Hogwash.
I will let God’s angels take care of me like they must have when I was that child sleeping by an open window. I think too many people are calling themselves experts who have forgotten what wind and water means.
Insofar as GPS and electromagnetism? Of course we have innate responses to such things. Our very bloodcells are made up of iron, which carries a special part of wind (oxygen) in a variation of proteins and saltwather/saline (serum) to feed our whole system. (Saltwater conducts electricity.) Electricity-Magnetism and a response to magnetic phenomenon has thus always been a part of us all.

I have no doubt that I do have an innate gps because even lost in a foreign market, I always found my way back to my train. In a new city, not knowing the street names, I could always find my way to my new home.

If you have deep roots to the area where you were conceived and born, you were made from the land, the minerals, the earth, and the IRON your mother consumed through the foods grown in that area. Her own mother too. Her mother beforee her. It would be rare to truly get lost there I think. Even after buildings, and streets changed.
We forget that we are made up of the air/wind/geomagnetism/subshine, the earth, the water, the metals, the plants and their chlorophyll (wood.) We are not something outside of feng shui/wind- water. We are part of it.

Hi Marcia,
Noted. Thanks for the suggestion!

Hi Marie,
Yes, you are correct. There is no default rule or blanket approach on sleeping directions. Sleeping with your leg facing the main gate is totally fine. Sleep direction is assessed based on the bedroom, not the entire house or lot.

Hi Joshua,
To your point, there are some Feng Shui masters who says electromagnetism is also behind the practice of Feng Shui. As for your home, I cannot confirm his finding just based on your home’s facing direction.

there is work on the history channel which states something about some type of earth grid which is related to electromagnetism. the great pyramid in egypt is a part of this concept. it is located at the center of gravity of the earth’s continents. it is stated that Stonehenge in england is also related to this earth grid. there is evidence that God or some type of highly advanced entity have the ability to manipulate gravity moving huge blocks of stone an aligning them to the stars or celestial phenomenon and i think that it relates to electromagnetism.

respectfully.

Hi Carmelina,
The idea is to avoid the bad before tapping into the good. There’s also the element of which Feng Shui school you’re practicing and what you’re trying to achieve. If in doubt, I suggest you find a professional.

Hi Brooke,
It depends. General rule of thumb is that the bedroom for the wife, and kitchen and front door for the husband. I have written a full article about this – https://fengshuinexus.com/feng-shui-rules/applying-feng-shui-couples-opposite-kua-groups/
Read to the end, because the house has its own Kua! These personal directions are just a way to mitigate IF the bedroom, kitchen, and front door locations are not in the best locations based on the house Kua.
