something new lands where the current is already gathered.
the motion holds: a center is drawing flow into one course. into that field, something arrives. what is new enters moving water, and moving water carries what enters. arrival and direction are present at once.
the new thing did not choose the current, and the current did not summon the new thing, yet each was already shaped to meet the other. the course was drawn before the arrival; the arrival was on its way before the course could see it coming. dawn works the same way: the light is new, and the land it falls on was already here.
