Does Buddhism give methods to ask questions when you are proliferating? From What is the Buddhist view in Socratic questioning?, I get that it is important to ask questions to get out of sufferings. However, when we are getting stuck it is very difficult to realize that we are stuck. With concepts such as sunyata, nirvana, papanca, dharma, detachment, does Buddhism have any guideline to ask questions in such situation? Or is the answer simply "when you are aware that you are in papanca, then try to get to nirvana and the questions will come"?
With concepts such as sunyata, nirvana, papanca, dharma, detachment

I suppose you internalise or become familiar with these concepts, so they (i.e. the concepts, not the descriptions of the concepts) appear (in your mind) as an antidote and/or a diagnosis when that's appropriate.

Analogously a couple of other concepts (from the suttas), perhaps fundamental, is to recognise, "this is (arising of) 'stress' (and/or craving, attachment), and this is 'cessation' (thereof)".

does Buddhism have any guideline to ask questions in such situation?

I think Buddhism recommends very simple questions.

For example, MN 61 (taught to Rahula when he was young) -- "Is this good or bad?", or more specifically


  This [...] action [...] — would it lead to (is it leading to, did it lead to] self-affliction, to the affliction of others, or to both? Would it be [is it, was it] an unskillful verbal action, with painful consequences, painful results?


This is a single, general-occasion or all-purpose question, suitable any time.

Another example of a question like that might be, Is That So? That's like asking, "Ok, so this is a "view", but am I sure it's true -- the only truth?"

There's Buddhist doctrine about "views" -- e.g. right view, wrong view, also cessation of views:


DN 34


  What four things should be given up? Four floods: sensuality, desire for rebirth, views, and ignorance.


(or more specifically "view-flood", possibly "flood of views")
AN 7.51


  Because of the cessation of views, monk, uncertainty doesn't arise in an instructed disciple of the noble ones over the undeclared issues

There are suttas (e.g. here) which seem to warn against taking views at all, and/or that "views" are one of the many things that a noble one is liberated from (I haven't found a good reference for this though, this might be an inaccurate paraphrase or out of context).


It warns that there are certain types of question that are inappropriate -- see A thicket of wrong views

I found this topic informative too -- How are &#39;conceit&#39; and &#39;identity-view&#39; not the same? -- helping to define what "a view" is or isn't.

Buddhism also (in my opinion) associates papanca with conceit, by saying they are both a cause (or are both the cause) of arguments (especially doctrinal or sectarian arguments) -- I suppose it's saying the motive is egocentric i.e., "I am right!", or, "My view is better!", and so on.

Or is the answer simply "when you are aware that you are in papanca, then try to get to nirvana and the questions will come"?

I was tempted to say, "That's not quite the answer: a better answer is ...", but I'd better not, isn't that so? :-)

"Trying to get to nirvana" is a dubious (i.e. possibly misleading) proposition -- on the one hand there is Right Effort, but on the other hand that might be the very definition of "craving".
