these are amazing! considering the objective power that symbols can carry, i wonder what effects looking at crop circles have on us? even if we don't consciously understand all of the meanings behind the images, they could well be programming us at a sub-conscious level. which begs the question, are the crop circles there as a warning/guide or as a threat/distraction? are they from friend or foe? this doorway one is very interesting, it also looks a lot like artistic representations of shamanic voyages (can't find any decent pics online, though they are some good ones from ancient tribal cultures in "the way of the shaman") .. could it be a steering towards collective expansion of consciousness?
the doorways to the sides look like they're the distractions in life; human curiosity could lead one to wander in through one of those, forgetting that we're meant to be heading towards the light! or, is it our purpose to explore what is behind every door along the way? the diagonal lines streaking across the whole image are interesting too, makes it look like a representation of a pane of glass; a reflection of our psyche?
