I read that book many years ago. I have it forgotten.

I've gotten to this information:

8th chakra: just above the head. The seat of personal karma and akashic records.
9th chakra: 1'5 feet above the head. Where the energetic DNA is placed.
10th chakra: 1'5 feet below the feet. Where the primordial energies find a way to enter the body.
11th chakra: surrounding the body and concentrating in hands and feet. It's an energy commander.
12th chakra: surrounding the previous one. The fringe of the human self.

I'm going to use the anthropomorphic method to work with them: meditation, giving them a human aspect and chatting with them.
