Does anybody know what a "caldron of becoming" is?

   Here's the context: a room full of artists, poets, ministers etc. discussing new ideas.

   "This place has become a caldron of becoming".

    My impression is there is something something missing here, in this sentence.
"Cauldron" generally is a boiling and bubbling pot where you cook food, meals etc.

     Not taking it plainly, it can suggest a place where there are plenty of ectic activity, many times putting people there under pressure.
     Maybe this is an example:

      Cauldron may be a difficult place or region to deal with, or that is likely to cause problems: 

http://www.mizozo.com/world/07/2010/07/the-caucasus-cauldron.html
"Of all the regions of the world, this one is among the most potentially explosive."

    Cauldron can mean a  fast transformation in an almost chaotic and random way, almost in a unrule way.    I have seen in the Web, a sentence with ''...the cauldron of teens becoming men.";  what suggest the turmoil this phase can be.

     It´s possible that the sentence "This place has become a caldron of becoming..." has to do this last definition (transformation in that way).  So it could be said in another way, for instance "This place has become a cauldron of transformation/changing etc"

    But, without much context, I stop my trying on clarvoyance here!
