IMHO There are many thoughts above that inspire in valuable ways.
I think the apparent hypocrisy of K is a separate issue. I am very free in telling others where I think I have been foolish, and likely self-deluding, but I have not seen K offer us such self-critique in order to avoid misleading thru his example. There's no value in passing judgement on him or jumping to conclusions about his intentions, but we're looking for all clues as to what he meant by his words and actions.
Several of K's statements act as valid criticisms of common approaches. However his words do not tie together as a whole and they ring hollow. The "logic" is flawed. Most truth-seekers seem pretentious to me. I try to be ever more self-honest, questioning myself harder when the answers seem to suit me conveniently, or justify what I do. Why theorize about a grand scheme that I do not understand?
Some key phrases to try to fit together: "living the truth" while being unaware of it. Being instead of becoming, altho moving from reality clouded by various illusions towards reality less clouded.
There are a lot of word games going on, and each of us understands them slightly differently, so I think it remains for each of us to try to fit them all together, or see how they don't fit. I try to finer-tune my ability to "smell" the underlying contradiction or vacuity (outright disproof is usually impossible in the face of possible ambiguity), while still trying to find as much inspiration as I can.
