Musar su Osea 4:17

Now it is known, that the upper "arousal" is dependent on the lower. Therefore, if the trait of peace is found in Israel, and there are no slanderers among them below, then in the upper world, too, Satan cannot prosecute them — even for the severest sin of all, idol worship, G-d forbid, as stated in Midrash Shir Hashirim, that even (G-d forbid) if Israel is idolatrous, but there is peace among them, the Holy One Blessed be He says, as it were: "Satan will not touch them," as it is written (Hoshea 4:17): "Ephraim is bound to idols — let him be!" The intent here is that the Holy One Blessed be He has implanted it in Satan that in such an instance [i.e., when Israel are at peace among themselves], Satan cannot touch them at all. And thus have Chazal said (Yerushalmi Peah 5:1), that the generation of Achav, even though they were idolators, would go down to war and win, because there was no slander among them. The proof — they did not slander [(to Achav)] Ovadiah, who sustained the one hundred prophets [who were hiding from Achav]. And, as I have written below, (Chapter IV), "measure for measure" is a [guiding] principle in all affairs. Therefore, if one suppresses himself and muzzles his mouth against speaking demeaningly against his friend and arousing strife against him, so, above, the Prosecutor, above, will not be able to open his mouth to speak accusingly. As opposed to a situation where there is slander in Israel below. For aside from the slanderer's arousing prosecution against himself because of his sins (as we shall explain below in the name of Chazal), he arouses the power of prosecution against Israel in general. For through this, Satan comes and prosecutes Israel for their sins, and calls for din against them; and [the L-rd], as it were, is "compelled" to punish them for this. And who caused all this?
