The manual is really well done. Anyone that has questions, many answers are in the manual.
He sites where all the info is from, who's research he is using to form the healing process.

The manual is a hard read in its entirety. In parts, its more manageable. When you get to the healing part, read that all at once. But get ready for a roller coaster of a healing.
Give yourself some time with it.

As for the beginning, I am in the medical field and I understand all that is being said. There is nothing that is 'funny' or unreasonable in the suggestions.

IMO, it truly raises your energy to a higher place.
