Reb Hillel of Paritch once said: “Lubavitch is a holy ‘Kaf HaKela[1].’ One is flung from here to there and one does not know in which world they are even in.”
(Likutei Sipurim, Pg. 304)
[1] One of the punishments of purgatory where the soul is flung across the universe. See the Mamor of the Mittler Rebbe, Yafa Sha’a Achas, Kuntreisim, for an explanation of this concept.
