Dear Derek and All:

DC> I'm going to take a stab at it and say that the relationship between

DC> papañca.

Carnivorous translators stabbing and devouring suttas ... :)

DC> So how about: "proliferation-induced perception-definitions" ?

Makes much sense and cohesiveness to my inexperienced taste.
Well, papañcasaññaa and papañcasa"nkhaa also occur on their own, so
probably "proliferation-induced perception and definition".

'Translator's Introduction' by Thanissaro Bhikkhu helped a lot to
smooth out my three furrows on the forehead :)
