I saw the most phenomenal piece of Torah in the writings of Rabbi Moshe Donnenbaum, a Rav, and Rosh Kehillah in Melbourne. In the 1800th century there was a huge macholoket (dispute) which ripped the Jewish world in two. Even the Vilna Gaon was unable to bring peace to the two camps. This dispute was between the followers of two giants and was clearly lasheim shamayayim (for the sake of heaven). Many of their followers stoked the flames of this dispute.
Many years later, long after the two protagonists, Rabbi Yonason Eibshitz and Rabbi Yaacov Emdin passed away, Rabbi Yonason Eibshitz appeared to one of the great sages of that generation in a dream. The Rabbi reported that both he and Rabbi Yaacov Emdin were enjoying each otherâ€™s company in Gan Eden while the stirrers of the dispute were still suffering in Gehenom. How could that be? It is well known that Gehenom lasts for a maximum of twelve months. Rabbi Donnenbaum explained that there are some exceptions to this rule. Regarding Machloket mongers, those who promote and ferment machlocket, their punishment or indeed their cleansing process for such a heinous sin, can extend well beyond the twelve months. So bad is this sin, one should literally ensure never ever to be involved. We see in the Parasha the way heaven dealt with Korach and his cohort of 250 for promoting through there speech and actions enmity within the camp of Israel.
I think it was Ronald Reagan, while president of the USA who said Peace is not absence of conflict; it is the ability to handle conflict by peaceful means.
