There are five levels of the light body taught by Duane and DaBen so far. (These are not the same as the 5 Light Body Consciousness levels)
These are:
Level 1: The Awakening Your Light Body six-volume course. This is required before moving to the next levels.
Level 2: Self-Exciting and Frequencies, (Building and Filling in Your Light Body)
Level 3: Light Body Consciousness, (Higher Levels of the Light Body)
Level 4: Infinite Being, (Upper Light Body)
Level 5: Luminous Body, (Beyond the Light Body)
