Likutei Moharan 183:2/ליקוטי מוהר"ן קפ״ג:ב׳

12. This corresponds to: The Sanhedrin was arranged like a circular granary (Sanhedrin 36b). “Sanhedrin” corresponds to the tzaddikim from whom come all rulings and livelihood, as above. And this is the aspect of “granary,” <corresponding to> sustenance and livelihood. As mentioned, they sat in a circle; <this is “circular”>. As the Talmud records, all this was so that they would see one another—the aspect of love, which is the aspect of seeing, as above.
