What moves is the film -- which is the mind

Q: Still, the movements of light have a cause.
M: The light does not move at all. You know very well that the movement is illusory, a sequence of interceptions and colour-ings in the film. What moves is the film -- which is the mind. (...)
There is only light and the light is all. Everything else is but a picture made of light. The picture is in the light and the light is in the picture. Life and death, self and not-self --- abandon all these ideas. They are of no use to you.
