Hi Anggrek

The energy flowing from the surface of the ceiling will be forced downwards when it reaches the cross beam. This creates a imbalanced downward chi. Depending on the vertical size of the beam and also the floor to ceiling height, the energy generated will affect the area below. Anybody or even living plants will absord this energy over a prolong period of time. Those people sitting or sleeping in that area will always feel stressful. Plants will not be healthy

                  ************  Place soft cloth beneath the entire beam

What you can do is to soften the protrusion of the beams by placing a bale of soft cloth underneath it. You can use your imagination to create a soft bland ceiling (kind of arabian night magic carpet effect). The color of the cloth must be in harmony to your room sector and also to yourself.

Feng Shui is all about peace and harmony to our environment.
