Ley lines are very visual ways to prepare for paranormal investigations.
So, it makes sense to put this information in a visual format: a mindmap. I’ve prepared it as a graphic (JPG) so you can print it for reference.
On the other hand, if you’re not familiar with my book, Ley Lines for Ghost Hunters, this chart may not make sense. (Or, it might be the overview you need.)
This printable chart identifies some of the key steps in successfully preparing a ley lines map to use for ghost hunting. It includes a few points not in the book, and omits some points described in detail in the book.
It’s not a full survey of ley lines and ley line construction, but — for ghost hunters — it’s a good overview if you are a visual learner. (I am, which is why I steadily use mindmaps in my work.)
