Excerpts from Book 3 CREATION: ITS HISTORY, EXPLOSIVE EVOLUTION, AND ET ARRIVALS ON EARTH. (Available on Amazon):
Green Aventurine – These frequencies are those of positive purposeful Spirit Enlightening energy. They literally help all Heart Energies flow throughout the body as well as your Heart Energy leaving your body.
(The Auric Expressions of Different Frequencies) Light Green – Here is the frequency of spiritual healing. Its shallow in depth and longer in length than the Dark Green. It helps clear and heal the Spirits within the body, very powerful. This creates and environment for happiness to grow in. Green Aventurine has these frequencies in abundance.
(The Auric Expressions of Different Frequencies) Dark Green – Here is the auric expression of powerful physical healing. The heart produces this to attend to physical injuries, the more serious the need the deeper the Green. The Spirit core also adds to this process. Dark green is a deep pulse with a short wave length and sharp edges. A Dark Green Aura’s frequency energy is a thick energy.
