If you read between the spaces, you’ll notice that I wrote “explicitly in detail.” I wrote that in both posts. Those words mean that besides for the actual Mitzvos of Lo Saalim, Hashavas Aveida, Ribbis and Pe’ah, there is a general Mitzva to be kind, generous and righteous. Just as there is a general Mitzva to follow the Chachamim while the actual individual Derabanan’s are not considered De’oraisa, the same goes for Middos. We can use Torah for a guide of proper Middos but each individual Midda is not on the level of a real Mitzva, while being a Baal Middos Tovos, is a real Mitzva.
Now, I sense a real misunderstanding here. The deeper meaning in any Mitzva is not in contradiction to the simple understanding. It is the deeper understanding. So, like I said, Geneiva is much deeper than making someone unhappy, but greeting someone with a smile is just that, making someone happy. The difference between a Mitzva and not a Mitzva is Rechok Shamayim Ve’aretz, and the difference between those Mitzvos which happen to apply to your friend and those that don’t, is nothing at all (other than the means of rectifying a transgression).
