"Life is a cycle of conceptual rebirths evident in what can be defined as consciousness. Far from being a strictly action/reaction agent, karma is at work during our physical lives albeit in an unfathomable manner at times (ie. great beings who suffer much)."
I think I actually agree with that. But I'm not sure. Can it be said any more clearly??
*Also* -- we need to phrase this in a neutral manner, not "X is", but "Some people think X is", or "X may be regarded as ..."
I think the opening sentence puts karma in the context of Eastern religion; it's not necessary to pepper the entire article with "Some people think..." and "It is believed by some that...". Besides, that's just bad style. ;-) --STG
