Hope it's helpful. To me, it explains a lot of issues that may occur and what to do with them. It can tell us why some partner combinations don't work whereas some may be very good or perfect for a lifetime. Many conflicts are there just because of different blood types and different personalities, too. It's better to avoid the complications. How many problems would have we avoided if we had known it earlier!

Enjoy!
