Rav Shach and the Rebbe

Rav Shach to Yosi Wallis: "The fact is Arachim does work all over the world, and in many of those locations there is no Yiddishkeit or kosher food... No Jewish infrastructure at all other than shluchim sent by the Rebbe. I think it makes a lot of sense for Arachim to work in tandem with the shluchim of Chabad, so as to accomplish the maximum for Klal Yisrael in remote areas around the world."

Rav Shach to Yosi Wallis in response to the Rebbe's blessing of him: "Please send my blessings in return, and tell the Rebbe that I wish him health as well. He's a good man, and he should be healthy and strong. Please pass on my wishes to him."
