Studying Degel Machane Ephraim
Children & shidduchimAhavas YisroelTorah learning
The Berditchever Rav, author of Kedushas Levi, wrote in his approbation to the sefer Degel Machane Ephraim, "I am assured that this sefer will enliven and inspire the hearts of our brethren Bnei Yisroel and set them aflame to serve Hashem." The Chozeh of Lublin said that the merit of its author, a gaon and godly man, will surely help all who study these words that came from his holy mouth, and that when they say them in the author's name his lips will move in the grave and he will advocate for us, because tzaddikim are greater in death than in life. The Ahavas Yisroel of Vizhnitz once told his son, the Damesek Eliezer, that the holy Rizhiner testified to his chassidim that merely studying Degel Machane Ephraim is a segulah for good children. In Yiddish: lernen in Degel iz mesugal tzu gute kinder.
