Concentrate on the natural rhythm of the decree, and repeat it three or nine times to begin with. Repeating the decree strengthens its power and draws down more light. In the East, mantras are often repeated thousands of times a day. Center in your heart and give the decree with love, devotion and feeling. Once you have memorised the decree, you can close your eyes while giving it and concentrate on visualizing the violet flame.
Visualization is essential to successful invocation of the violet flame.
When you decree, you are actually creating by using God's energy within you. You cannot create what you cannot visualize, just as an artist cannot paint a picture he cannot see. See yourself before a large bonfire, about nine feet high and six feet wide. Colour it violet in your imagination, and see the flames undulating in endless shades of violet with gradations of purple and pink. Then see yourself stepping into the flame, so the violet flame is where you physically are.
