Menahem Mendel perpetuated the doctrines of his mentor, the Maggid of Mezhirech, utilizing the kabbalistic concepts of emanation, tsimtsum (see Luria, Isaac and Lurianic Kabbalah), and Atsilut to explain the relationship of man and God and the possibility of communion through Devekut. To attain the desired state, Menahem Mendel urged self-abnegation, devoutness, and the cultivation of moral values. His main works, published after his death, are Peri ha-Arets, Peri ha-Ets, Ets Peri, and Likkuté Amarim.
