Can this question be asked? In Buddhism, If I ask the following question:


  Suppose you completely empty your mind of all thoughts. You go into complete emptiness of mind, where nothing is arising.
  Suppose that in that state you make a choice to arise a thought. If in that state a choice is made to arise a thought, "choice" is the arising of "this thought".
  "Choice" must be arisen before "this thought" is arisen.
  Is there something that must arise before "choice" in order for "choice" to arise?
  If there is "something that must arise before 'choice' in order for 'choice' to arise", is there something that must arise before "something that must arise before 'choice' in order for 'choice' to arise"?
  etc. etc. etc.
  So, where does it end? 
  What is the first "thing" that arises in your mind before the rest arises out from this first "thing"?


Does the above question fall into the category of the Four imponderables? Specifically "The jhana-range of a person in jhana... [i.e., the range of powers that one may obtain while absorbed in jhana]"? http://www.accesstoinsight.org/tipitaka/an/an04/an04.077.than.html

If yes, why? If no, why?
Knowledge has limits.

"Mind is not Buddha. Knowledge is not the Way." But then, even saying this is leading you astray again, so I should shut up. Your question can be asked, because you have asked it. But not all questions make any sense. I think that the error is the choice of your second word, "Suppose you..." This word has no referent. But to communicate with you, I need to resort to meaningless terms like 'you' and 'I'. Try not to get hung up on them.
