itself essences as the essence of technology. The essence of technology is positionality. The entrance, as event of the turn of forgetting, enters into what is now the epoch of beyng. That which is, is in no way this or that being. What authentically is—and this means properly dwelling and essencing in the Is—is solely beyng. Only beyng “is,” only in beyng and as beyng does there take place what the “is” names; that which is, is beyng from out of its essence.
“To flash” [blitzen], according to the word and the issue at stake, is to glance [blicken]. In the glance [im Blick] and as the glance, what is essencing enters into its own illumination.

At first and almost to the very end it appeared as though “insight into that which is” signified only a glance that we humans cast forth from ourselves to that which is. “That which is” one customarily takes as a particular being, for indeed the “is” is said of beings. But now everything has turned. Insight does not
