Don't search for a door, not even in a metaphorical sense. There's nothing non-manifested hidden somewhere. The absolute is in plain sight when you look at the relative. In fact, if you cannot see it that way, you've yet to see anything.

In any case, the question in your case is more like what happens when you don’t look for ghosts in a place that you think doesn’t have any, but you still suspect that there may be some?
