“the white light flowing from the projector is a metaphor of consciousness. In the awake state, the physical world acts like a roll of film creating patterns in the light. Your consciousness is filtered by the physical world and you are therefore aware of your surroundings. In the dream state, the roll of film is provided by whatever memories or experiences generate your dreams—an interesting topic in its own right, but not relevant here. In both cases, consciousness manifests the objects that are filtered from it—the images on the film in the analogy. In the case of deep sleep, the plug has been pulled on the projector; there is no white light. Russell argues that the fourth state of consciousness is that of the pure white light itself, not filtered or affected in any way by the objects of consciousness. This pure self-awareness is your ultimate consciousness. It is reported to be a state of peace and bliss—an awareness that the pure consciousness experienced is but a concentration point within a single universal consciousness.”
