The Teachings of Rebbe Pinchas of Koretz and His Disciple, Rebbe Raphael of Bershad
“[G-d banished man from the Garden of Eden.] He drove away the man, and stationed the cherubim at the east of Eden, and the fiery ever-turning sword, to guard the way to the Tree of Life (Genesis 3:24). R’ Pinchas said: ‘The fiery ever-turning sword has a universal meaning for all of us. It represents the obstacles and temptations we encounter in our attempt at achieving closeness to G-d. G-d is the Tree of Life and there are many deterrents that block our path to him’”.
–Imrei Pinchas HaShalem, Bereshit 8 (A, B), cited in The Great Chasidic Masters, by Avraham Y. Finkel, p. 35 (B)
