Street Farbrengen Episode 40 - 19 Kislev - and the modern Heavenly Accusation

ChabadLife.TV Street Farbrengen

"That year, during Tishrei, the Rebbe was extremely joyful. He mentioned to the chassidim who were close to him that he had not yet made a seudas hoda'a for his geula, as one is obligated to do, al pi halachah. From this, they understood that the coming Yud-Tes Kislev would be something out of the ordinary.”
What do I learn and use as a guide that the Alter Rebbe waited one full year to make a seudas hodaah, a thanksgiving meal?
Street Farbrengen thinks of a current kitrig, heavenly accusation against Chassidus today and waits for a modern thanksgiving meal!
