Vaastu and fensghui.     In vaastu we do not use the general one as north east is for swami room and south east is for kitchen. We believe that each and every person directions are different.each one ahs negative and positive directions depending on the horoscope.this will done for all the family members . the plot will be inspected also. Then there specific measurements for over all size of the plots , for lintal etc. these are based on yoni. There are 8 yonis in vaastu. In fengshui we follow the methods of nine ki star and 8 pillars which are considered the best methods.
