I have a question concerning the bagua... I live in a tiny studio apartment, but I think I've done a good job of giving each section of the place a distinct yet harmonious flavor. Throughout the years, I have had a frustrating quandary: some people say the bagua needs to be laid over the home using cardinal directions, and others say the entrance starts on the water side of the bagua (Career/People/Wisdom). I don't know which one to believe. Is there a definitive answer on this? Thanks so much.
