While I appreciate the point you are making, and I do, your assumption is that by 'arrival' I mean that it is a static condition. To the contrary, it is a very dynamic condition, but one in which Everything is to be found right here, right now, including 'new' discoveries and experiences. The difference I am pointing up is that now, having arrived, all your experiences are full and complete, as contrasted with the seeker, who is forever looking to some imaginary non-existent future. We pretty much know, via direct experience with any such imagined future, that things never pan out the way we imagine them to be, but direct experience with Reality in the here and now, without expectation or preconception, is always exactly what it is; always fresh, new, and alive. What we call the 'future' is actually a vision based upon the past, and therefore, is dead. When we live fully in the Present Moment, life is an ongoing flowing experience from one moment to the next. To never arrive in the Present is to not be here, now. Are you here, now, or are you somewhere else?
To say that one has arrived does not mean that one now knows everything; it only means that one is now focused on what is going on in the present moment, rather than having one's attention diverted to the dead past or to the imaginary future. Only the present moment is Reality, so arrival is to be fully present, here, now.
We are indoctrinated with the notion that the past builds up to create the present, but that is just an illusion. The reality is that the present is what creates the past. The dead past cannot create the living present; it's already dead. It only trails off from what is occurring right now. The ship creates the wake; the wake cannot create the ship.
