"Rabbi Feivi Arnstein has made a major contribution to the world of Chinuch with his book, "The Master Mechanech". It sets forth the principles of education according to Chazal and the Gedoley Hadoros. Rabbi Arnstein, an expert Torah teacher and principal, presents in this book what should be the guiding lights of every Torah educator. Every teacher who seeks to evoke the utmost from his students will gain immensely by reading and implementing this book."
Rabbi Aharon Feldman
לכבוד הרב המופלג ר' פייביש ארנשטיין שליט"א,
ראיתי את הקונטריס שאתה מוציא לאור בעניני חינוך. נראה שיש בו עצה ותושי' למחנכים ועוד דברי חיזוק לעבודתם הק', ובטוח אני שימצאו בו דברים הרבה שירויחו מהם באופן חיובי.
ברכתי שתמשיך לזכות את הרבים ע"י הוצאת עוד ספרים אחרים ושיהנו מהם כל המעיינים בהם.
הרב שמואל קמנצקי
"HaRav Feivi Arnstein has dedicated his heart and soul to bolstering the chinuch of our children, and has produced a very important sefer, explaining the fundamentals of chinuch for rebbeim and moros, the teacher-talmid relationship etc. He explains the rebbi's role as not merely the teaching of text, but the emotional underpinnings of a committed yid and ben or bas torah. It is all based on impeccable sources, in close coordination with HaGaon Harav Aharon Feldman shlit"a.
In times like ours, where on the one hand, we seem to have so many schools and resources available, yet we watch with trepidation at those who somehow fall through the cracks and whose commitment becomes shaky, this is a crucial and timely work.
May Hkb"h bless our efforts to be mechanech the children of our dor appropriately."
Rabbi Ahron Shraga Lopiansky
