in a meng hu post today (about haiku) he says:

"For the way does not consist in triumphantly proclaiming that we have learned something, learned anything. Conversely, we must not proclaim that we are ignorant, that we do not know, that we have not fathomed any mysteries. We must be comfortable with this quiet insecurity, this not-knowing. No shame attaches to us as if this not-knowing were a failure of diligence and intellect. Rather, it is that we cannot apprehend , we cannot reason our way into the mysteries of existence. Everything in nature shows us that".

apprehension is not necessary to progress I think.

when there is no apprehension, it isnt to say we cannot continue:

we can continue - even in total darkness, even when we don't know where our next footstep will take us. then is the time for trust.   

This is a power which you have given us, and not just on good days: to always be able to walk forwards, if only we will it.

that doesnt sound quite right, because when I say we will it, it is really only you who will it - I know this - but you give us an ability to will as you will.

"your will be done" isnt then a vague hope for what might one day be, but a statement about a reality that is here and now just as you are here and now.

"progress" is not really the right word, because progress is not necessarily progress in the sense that we understand it. It might really mean "no-progress-at-all", but that will not matter because we" walk on through" anyway.

 . . . .  and so, the progress is made because we learn to make progress without necessarily making any progress at all; despite everything in fact.
