Epistrophē · the return

The turning-back: everything that proceeds from a source also yearns toward it, and the descent is only half of the figure — reality is a circuit, not a fall. Proclus's triad is remaining, procession, reversion. The Tree runs the same circuit: the lightning-flash down through the sephirot and the returning light back up the pillar; ratzo va-shov, running and returning. And Judaism's word for the turn is teshuvah — literally "return" — which it makes not a metaphysical necessity but a moral act you can choose on any given afternoon.
