If you work in an office that has spectacular views do not be tempted to position your desk so that you are facing the vista at all times. There are several reasons for this: first, you will be looking into activity, which is considered yang in nature. This will prevent you from concentrating fully on your work. In addition, you may also become desensitised to the view, with the consequence that it becomes 'wallpaper'. Finally, the sunlight that filters through will impair your concentration, especially if it is from the setting sun, as that is of a yin quality, being light that belongs to the end of the day.
Neither should your desk be placed directly against a wall. The Ming Tang or Bright Hall formation - the principle that there should always be some space ahead of you that will allow positive energy to accumulate - will not be able to work its magic. Facing a wall at work means that you may encounter setbacks, obstacles and frustration.
Ideally, you should face an open space that does not look directly at a door or a window so the Bright Hall formation is simulated. It is preferable to position your desk so any view is to your side and you can look up when taking a break to fully appreciate it.
