Killer, it’s helpful if you post a link to the Staff Report that you are commenting on, helps others figure out what the heck you’re talking about. Makes for more coherent responses.
Well, there, that’s enough of that. Evidently the word “sindhava” or “sindhu” or “saindhav” can be translated as either “rivers” or “seas”, depending on the translator, I suppose.
As for what happened to the other two rivers, or whether there even were seven rivers to begin with, I’ll leave that for somebody else to deal with, 'cause I’m going to bed.
