Dear Cecil, based on your advice, the best rm is 1 at south which is currently occupied by me , yet my health has been going bad, is it likely that external south sector construction of a new building has activated the mountain star thus affect my health? What remedial is there to reduce negativity in these problematic rooms? I can leave out one room but would need two usuable rooms. Please give me advice to fix this other than to change house. I read on some website , the use of salt water as a fix it for negative energy, is this a sensible thing to do ? Rm 1: S sector, MS7 , WS7 , BS2 Rm2: SW sector, MS9, MS5, BS4 Rm3: W sector, MS5 , WS9 , BS9
