Instead of preface: good deeds (Maas tovim) are those things that are done with the motivation "for the sake of Heaven." All the others, even the super-kosher in appearance, actions only reinforce the clip, sharing light with impurity.

We, the Jews, you should not get into the affairs of other nations, teaching them to live and so on. Others can only correct, correcting itself (and thus their fixing part in the other). At the level of societies means that we need to build at a just society that want to take over other nations.

But do not get involved in other people's wars, because there is not no friends or enemies ..

PS Correction is finding motivation "for the sake of Heaven"
