Why is it relaxing to have a clear view of your bedroom door from your bed?

Question

Was told that this makes your "feng shui" more decent... why is that?

Answer 1

It's due to the ability to see anything that might come at you from that direction. Your body will relax as your mind won't focus on keeping you alert to what might be coming up from behind you or from the side. You should keep your bed on the wall with no windows and no door, but in a position where you can see all of those things. You'll feel more secure without even thinking about it. Your living room should be the same way. All rooms should be actually. Kee the door in plain view. Don't have openings that are behind you that people could sneak up on you. If you were to have no choice in the matter and have doors on each and every wall, place mirrors around so that you have an open view of it all.

Feng Shui is to help keep a flow to your entire home. Most houses are not built for proper feng shui. But there are things you can do to help. Also make sure you keep the elements around. Wood, water, fire, metal and earth. It's very important to keep those within your home.

There are many books on the subject.
