Lena explains what Kuan Yin is telling her about the EEG periodicities: "These protective elements (the brainwaves) help our human bodies function and survive on this earth plane. However, this discussion involves the soul. Gravity holds our physical bodies in place. Our skin holds the spirit in place. Heavy layers of energy, karma (around the earth and the body), weigh us down. Every layer is different. The brain waves represent the different layers of consciousness. Each brainwave is a sort of gelatinous substance; layer upon layer; much like the onionskin metaphor. Accessing a certain layer accesses certain abilities [i.e. trance skills in the alpha range, dream abilities in the theta range, etc.]. They all work together perfectly. When an individual "hits" a certain layer, he can work (heal) certain issues.
