So it's the third of GPs options:

> achieving mystical realizations along the lines of zen koans

Except that there's really nothing mystical about zen koans, if mystical is meant in a derogatory way as vague mumbo-jumbo. Zen koans are trying to do the same thing as Wittgenstein is (according to the parent - I haven't read him): lead the thinker to recognise the limitations of language, and in particular its inability to fully express ideas about its own limitations. The response "mu" unasks the question, indicates that the concept has been understood but the question itself seen as nonsensical.

That's my understanding anyway. I haven't practised Rinzai Zen, the one that emphasises koans, but only Soto Zen, which mostly eschews philosophising in favour of just sitting quietly.

>lead the thinker to recognise the limitations of language, and in particular its inability to fully express ideas about its own limitations

Right, I think that's a good way of putting it. He even writes in the Tractatus about how we can see with our eye, but we can't "see" the limits of our visual field. (Edit: I see now that GP mentioned this, which I missed while skimming.)

I think Wittgenstein would have credited those higher meanings with significance and not divided them as mumbo jumbo. In a way you're supposed to apprehend that those things that mean the most are not the things that language is capable of representing.
