Reading the Letter from Hashem on Shabbos & Getting the body to Celebrate with the Soul

From B'yam Darkecha on the Beauty of Shabbos & the Yomim Tovim: R Yossi Michalowicz by R Yossi Michalowicz.

pp.405-413: Moshol of the Ba'al Shem Tov about the captive prince who receives a letter from his father saying that he has not forgotten him. The Prince celebrates with the other captives by getting them drunk. The seudos of Shabbos are a continuation of your Tefilos - not a break from spirituality.
