Rabbi Levi Yitzchak (b'Reb Meir) of Berdichev z"l (1740- 25th Tishrei 1809) is considered one of the founders of chassidism. He was revered and beloved as the "Defender of Israel" because of his compassion for every Jew. Rebbe Nachman called him the Pe'er (splendor) of Israel.
Likutey Moharan 2, Torah 67 - "Bereishis - L'Eynei Kol Yisrael" was taught by Rebbe Nachman on the 27th of Tishrei 5570, on Shabbos Bereishis. Although news of Rabbi Levi Yitzchak's passing hadn't yet reached the Breslov community, Rebbe Nachman was aware of his petira and composed this hidden eulogy for him. In it, the tzaddik ("Rosh Bayis") is compared to the Beis HaMikdash. (Parparaot LeChokhmah.)
