Hello, I am quite confused about which direction to use for analysing a natal chart of house. i have read some posts but still not clear. If main door is the mouth and chi flows in through here so obviously this should be used to establish the flying stars chart. Yet what if this is a flat with darkish hallway but the windows of the lounge face the street and sea and let in more light? But these windows are never opened (due to extreme heat outside). what then? I am trying to figure whether to use the windows which is NE3 or the door SW3. would appreciate any advice, Thanks.
