The Zen master Huang Po (d. 850 AD), whose teaching can be found in The Zen Teaching of Huang Po: On the Transmission of Mind, gives you no conceptual handles to hold onto. In this regard, his teaching resembles The Avadhuta Gita, which is a deconstructive wrecking ball also.

Huang Po won’t, just won’t let you get comfortable with practices of any kind–for how can any practice lead one to Enlightenment when Enlightenment is omnipresent? Nor with any distinctions at all–like that between now and then, self and others, objective and subjective, unenlightened beings and enlightened beings, being mind and Mind, samsara and nirvana, and so on. How can the perfectly white page that is Mind admit of any India ink scrawled across it? Impossible!

What makes his teaching uncompromising is that he won’t budge an inch in his replies. He gives you nothing, cold comfort. Indeed, any sticking point you have, any assumption you’ve not examined, any form or idea you’re holding fast to–just drop it!

He has, in fact, nothing more to tell you than that you are–right now!–to bring all conceptual thinking to a halt. Since you can’t think Pure Being, stop it! Since you can’t know it, don’t try! Since Mind is right here, fall down! In a word, put “it all” down!

Call this teaching “radical self-inquiry.” Only see that the question is the answer.
