There are three main ingredients in modern orgone energy devices; resin, metal shavings and/or powder, and crystals.
The type of metal used is a matter of preference. Most orgone energy workers agree that aluminum, steel, brass, copper & gold are good choices. The metals compressed in the resin create a filtration effect.
Like plants, crystals are our friends in the nature world that also have healing abilities. Quartz or stones that are similar in properties are typically used in scalar energy for their ability to amplify as well as restructure energy. Other stones may be added for enhanced effect.
The more I work with crystals not only in creating a harmonious environment through scalar energy, but also in my reiki healing sessions, the more I am amazed at what they can do. Below I list a few things about the crystals I typically use in my orgone generators.
One thing that is neat is that the color of the crystal generally corresponds to the color of the chakra it is associated with healing. When choosing what crystal or crystals are best for you, follow your own intuition. Whatever you are drawn to is usually exactly what you need.
