Those are the words of the Chofetz Chaim in his sefer Ahavas Chessed in regards to the subject of achdus and chessed (loosely translated): "How good it would be, if this matter were to spread in our nation, the holy people, and all would hasten to this mitzvah (of chesed). This would cause the whole world to be filled with the מדת החסד, and all the troubles and tribulations would be eliminated from the world.
This can refer to the meaning of Chazal's saying in Tana Debei Eliyahu (which was mentioned earlier). "When the Yidden were in Egypt, they all gathered together, and made a covenant together to extend kindness to each other". Making a covenant "together" means that everyone, the wealthy and the poor, tried with all their might to help and assist each other in any way they could. This middah of kindness and unity among them was one of the things that brought the Geulah. May Hashem with His bountiful mercy strengthen us with this holy middah, and this we will merit all good in This World and the World to Come".
(אהבת חסד ח"ב פי"ד)
Let us ensure to strengthen ourselves in our unity, remembering that we are one nation and essentially one soul. May we remain vigilant about this superior value, and abstain from Lashon Hara, constantly being conscious to guard our tongues. Just like the Yidden in Egypt were redeemed from exile as a result of their achdus, may we too merit for all of Klal Yisrael be zoche to the geula sheleima speedily in our days. Amen!
