- The impediments on the path are described by the author in volume three, based on the books 10, 11 and 12 of the Corpus Hermeticum. He makes clear to the reader that a new attitude of life is a necessity. A new desire in the heart attracts light force, which influences the blood. The blood, charged with light force, subsequently enlightens the head and induces a new thinking! This sus-tained new attitude of life is the gateway to the mystery temple.
