My grandfather said that the Mitteler Rebbe wrote specific maamarim and a special book for every different kind of maskil and oveid1 in the Chassidic community. Shaar Hayichud and Shaarei Ora, however, are general, written for all chassidim. Shaar Hayichud is the key to the teachings of Chassidus; Shaarei Ora is the alef-beit of Chassidus.
