Likutei Moharan 65:9/ליקוטי מוהר"ן ס״ה:ט׳

19. And this is the meaning of: In time to come, the Holy One, blessed be He, will make a circle of the tzaddikim. [He will sit in their midst in the Garden of Eden], and each one will point with his finger [and say, “this is God in Whom we trusted”] (Taanit 31a) .

2“A circle” is the aspect of joy, which is the vessel for receiving Torah, as explained above. All [enhanced Torah insight] is the product of self-transcendence. As was brought there, the radiance of the trace that remains from the transcendent state is the source of the Torah [insights received] by way of the vessels.

3This is the meaning of “point (mar’eh) with his finger.” Mar’eh alludes to the trace’s mar’eh (appearance) and radiance, from which Torah [insight] comes. This is “point with his finger”—an allusion to the Torah, which is an aspect of “the finger of God” (Exodus 31:18) .
