The
Baal Shem Tov, or Besht — the founder of Chasidism —
met the soul of the Messiah during an ascent to heaven.
The Besht asked him, "When will the Master come?"
The Messiah answered, "When your wellsprings break forth to the outside!"
(from a letter
written by the Besht to his brother-in-law about one of his soul ascents)
