We use Generators for a number of reasons, to help with channelling, lifting our vibration and meditation. We also use them when we want to create a certain atmosphere in the home. You may  use a rose quartz generator in the bedroom to amplify a loving environment. A fluorite generator can be placed in the area of the home that needs more clarity and harmony (office, lounge etc). Make sure you keep your generators cleansed so they are not generating any lower vibrations back into the home or your aura!
