These 3 centers represent higher,lower self and the middle meeting place which is heru. These are the places from which you speak. Everyone's "set" or second seat or sacral chakra is different. You must balance them and learn of them before.
I didn't exactly know this I had this book got it from a library and didn't read it til today lol but I knew this before seeing it and was able to make decisions from lower, or higher self and making sure its the right decision with heru.
Learn about yourself.
Whats the book called?
It's basically about being in control of the devil and of God and knowing the difference.
