What's the benefit about knowing the position of the Grand Duke for each year?
This is because sitting opposite or facing the Grand Duke will bring you
misfortune, calamity, disaster or defeat.
How to improve your environment after knowing the Grand Duke Theory?
Avoid sitting in a direction facing the grand duke as this will bring
disasters and grave misfortune in that year.
I am interpreting the first explanation to say do not sit facing the Grand
Duke and I am interpreting the second explanation to say do not face the Grand Duke.
I am okay with so far, but then you say "For example, if the Grand Duke is in the North Direction, then sit facing North." Isn't this the same as facing the Grand Duke?
What I need to know is this year the Grand Duke is East, 90 Degree. Should I sit facing East or West?
Overall, the Grand Duke Theory for most of us is related only to the renovation of our home. That is this theory is widely used by Feng Shui Masters to guide home owners and caution them where not to do a major renovation.
Other than this, you need not be concerned with the Grand Duke Theory although it has one portion that says about the `sleeping' position. For `sleeping' position, it would be best to use the Eight House Theory i.e. if your North direction e.g. is a good or auspicious direction e.g Health, Prosperity, Longevity or Excellent, then you should try to sleep with your >Head, facing this good direction.
