and toward the regions to the southwest, boundless, like the east wind, if it be allotted to the eastern regions, and the other likewise toward its own regions, you will see the drift of the vision.

This is the rite at its most technical and its most obscure — a note, half lost to us, on which way the pipe of wind and the whole vision will 'drift' (apophorá), reckoned by the quarters of the compass: the southwest (líps), the east (apēliṓtēs), each pipe swinging toward the region it is 'allotted' to. Preisendanz marks the Greek here as troubled, and any honest translation has to admit the machinery is only partly legible to us. What comes through is the mindset. The vision is not free-floating; it has an orientation, a direction it leans, read off the winds as a sailor or an augur would read them. The initiate is being taught to notice not just that the gods appear but where the current of the appearance runs — the rite treats the ecstatic experience as something with a weather, a set of the wind, to be observed with the same care as its words.
