"Beyng" is not the dominion of a "subject." Instead, Da-sein, as the overcoming of all subjectivity, itself arises out of the essential occurrence of beyng
181. The leap
is the opening-up self-projection "into" Da-sein. Da-sein is grounded in the leap. Grounded through the leap is that to which the leap leaps as opening up.
Self-projection: the self first becomes proper to "itself" in the leap. Yet that is not an absolute creation; on the contrary, the thrownness of the self-projection and of the projector opens up abyssally, very differently than in the case of the finitude of the so-called objectively present creations and productions of the demiourgos.
182. The projection of beyng.
The projection as thrown
The projection at issue is always only the one of the truth of beyng. The very projector, Da-sein, is thrown—i.e., appropriated—by beyng.
The thrownness happens, and at the same time gives testimony of itself, in the plight of the abandonment by being and in the necessity of the decision.
Inasmuch as the projector projects and opens up the openness, this opening up reveals that the projector himself is thrown and accomplishes nothing but the catching hold of the oscillation in beyng, i.e., the entrance into the oscillation and thereby into the event, and so first becomes the projector, namely the preserver of the thrown projection
183. The projection upon beyng
is unique, indeed such that the projector of the projection casts himself out into the open realm of the projecting openness in order for the first time to become himself in this open realm which occurs as ground and abyss.
"Entrance into the openness"—that erroneously sounds as if the openness were already there, whereas it comes to be in the first place, and only, with the very dislodgment into it.
