Every natural effect has a spiritual cause and not a natural one. A natural cause only seems to exist. It is a delusion of the perishing vegetable memory. We do not remember these moments in time when we imagined certain states. When that imaginal state takes form we can see it with the outer eye; we do not recognize our own harvest and deny that we had anything to do with these natural effects that are taking place in our world.

Because our memory is faulty, we do not remember. Blake said, "There is a moment in every day that Satan cannot find, nor can his watch fiends find it. But the industrious find this moment and multiply it once it's found, it renovates every moment of the day if rightly placed." Now, by the word "Satan," he simply meant doubt. Doubt cannot find it. I desire a certain state in this world. Reason tells me it's difficult - my friends tell me it's impossible - so if I doubt I could ever realize it, that's the voice of Satan speaking to me. He's always challenging God.
