PRECIOUS HOURS
The Frierdiker Rebbe related, in the name of his father, the Rebbe Rashab: "The 48 hours of Shemini Atzeres and Simchas Torah must be held very precious, for at every moment one can draw pails full and barrels full of treasures, both b'gashmius and b'ruchnius. This is accomplished through dancing."

A certain chossid, distraught, once made a long trek to visit one of our Rebbeim. (When the Frierdiker Rebbe narrated this incident, he added: "And I'm not going to tell you who was the chossid and who was the Rebbe.") That chossid had come to report that his mentor had come to him in a dream with fearful news: It had been decreed in Heaven that one of his children would pass away. The Rebbe heard his words, sighed, and did not answer.
Since it was before Succos, the chossid remained near his Rebbe until after Yom-Tov, and before returning home, he asked him for a beracha. The Rebbe said, "It will be good; the child will live."
The chossid asked the Rebbe for a promise that this would be so. The Rebbe promised, and then asked him, "What did you do on Simchas Torah?"
The chossid replied, "When everyone was dancing at hakafos I stood by the oven and cried. But then I reminded myself that it was Simchas Torah, so I washed my face and went to dance with the Torah."
The Rebbe replied, "You should know that by doing so, you reversed your situation."

Once, while dancing during hakafos, the Frierdiker Rebbe (before he was Rebbe) told a certain chossid: "Granted that we are not up to the avoda of Rosh Hashanah and Yom Kippur. But the avoda of Simchas Torah - dancing - that we can do. So dance! Raise yourself up!"
