The previous Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn, writes in a letter:
The “Grandfather of Shpoli”was known for his exceptionally warm and ebullient nature. When he was in Liadi to see the Alter Rebbe (this was in the year 5669 or 5670), he related: “When I was three years old, I met the Baal Shem Tov. He placed his holy hand over my heart, and from then on, my heart is warm.”
“A single motion of a tzaddik,” concludes Rabbi Yosef Yitzchak, “how much more so the sight of him and the sound of his voice, should never be forgotten.”
