I said that there was a theory about light defining bright planets as benefic and dimmer planets as malefic. Rawiri referred to the naisargika bala, and as you see the list you posted is--- exactly what he said.
He said that they are related to luminosity, but then said this wasn't exactly so, and apparently the scale was done more so for the order of the planets. I can't agree or disagree on that, I don't have much knowledge of vedic, so I would let that to rawiri to explain what he meant.
But on this case you posted a list that shows exactly this that the 2 benefics are brighter than both malefics:
3. Venus (-4.89)
4. Jupiter (-2.94)
5. Mars (-2.91)
7. Saturn (-0.49)
So I guess, thanks for again posting the demise of your own argument? Because it is clear that both benefics are brighter than the malefics. So this pretty much confirms the theory.
You are also, dodging his coments on the waxing/waning Moon, a subject which I did mention earlier regarding the concept of "light" when applied to the Moon which we haven't even touch.
So let me add some more examples: in traditional Horary we use the concept of translation of light, in fact it is an important factor in Horary; so denying that traditionals don't use the concept of light, is just denying fact.
But cheers!
