If you’re comfortable with the Tarot already then I 100% agree you should have this book. Most professionals probably already do.
If you’re just geting started and looking for a Tarot book then Liz Dean is a better introduction to how it all works and how you can start doing readings. I think 78 degrees might actually scare beginners off.
This is what I used to learn and you can honestly start doing decent readings on your first day.
