Ezekiel 8:12 - son of man, have you seen what the elders of the house of Israel are doing in the dark, every man in his room of pictures? Neville uses it for the secrecy of imaginal acts: we think no one sees us, and nothing is hidden. God never forgets, cannot forget, watches all and sees exactly what you are doing. The point is not surveillance but consequence - the picture entertained in the dark room is a seed already planted, and it will come up whether or not anyone ever learns who planted it. His worked example is a memorandum written in secret and filed for forty-three years before its harvest arrived.
