Question:
My neighbor has this LuoPan hung above his car porch pointing towards my house. What am I going to do? Should I use a fork and point against it? I thought LuoPan is supposed to be a tool, just liked what you are using to measure my house.
Answer:
There are many taboos in relation to the LuoPan. Liked YinYang, it may be true for some aspects, but yet false in other aspects. Like in your case, if you think the LuoPan is just a tool, yes it is a tool as a compass to measure. Yet, beyond that it is also a vessel. Any physical object you see and is empty within is potentially a vessel. Being an empty vessel it is potentially to be occupied by entities. This is not FengShui per se. That is why it is true in some aspect, yet false in the others. Your neighbor has used the LuoPan as a vessel for the residing guardian spirits to protect his house. So, there is nothing you need to do about it.
Saying thus, there is a practice in Yin FengShui, where it is thought that the LuoPan may be possessed if you place it directly on the ground. So, you need a bucket of uncooked rice to rest your LuoPan with. This is again, not FengShui, yet it is true in another aspect. Same goes with the fact that some old masters refuse to open up the LuoPan when the sun is set. There are some truths in that.
In the years of practice, sometimes we are not able to take measurements with our LuoPan for certain unknown reasons. We may blame it to the unstable Qi fluctuations. Yet, there are far more reasons to that.
