How Much Concentration Do We Need?

One of the questions that comes up oftentimes is how much concentration do you need to do this work?  So, you get various debates in Theravada Buddhism about how much you need to get to various levels and so on.  Sometimes you’ll hear opinions about that, which are grounded in meditators’ own insights, or assumptions, or readings, or whatever.  Obviously you do need some concentration.  Concentration is a very important part of developing the mind.
