Speed Learning Numerology (Recommended)
SPEED LEARNING NUMEROLOGY EBOOK
When I bought this book I didn't really know what to expect, but this is the book I learned Lo Shu from and I highly recommend it. Not only does it give you shortcuts to memorizing all the number and arrow meanings, it includes a 4-phase routine to give someone a full-in-depth reading using Lo Shu!
Best of all, the Lo Shu Deck and the Speed Learning Numerology book both use the same definitions for the arrows and numbers, so they work perfectly together!
