Here’s an explanation of the five levels of energy that you work with, moving from the lowest and slowest frequencies to the high­est and fastest.

• The material world. Solid form is energy slowed down so that it’s approximately commensurate with your sense perception of the wodd of boundaries. Everything that you see and touch is energy slowed down so that it appears to be coalesced mass. Your eyes and your fingers agree, and there you have the physical world.
• The sound world. You seldom perceive sound waves with your eyes, but they can actually be felt. These invisible waves are also high/low and fast/slow. This sound level of energy is where you connect to the highest frequencies of Spirit through the practice of Japa meditation, or the repetition of the sound of Cod, as I’ve written about extensively in Getting in the Gap.
• The light world. Light moves faster than the material world and faster than sound, yet there are no actual particles to form a substance called light. What you see as red is what your eye perceives a certain pulsating frequency to be, and what you perceive as violet is an even faster and higher frequency. When light is brought to darkness, darkness becomes light. The implications for this are startling. Low energy when faced with high energy expe­riences an automatic conversion.
