The Tosher Rebbe used to say that “The sefer, Likkutei Amarim also known as Tanya is among the most fundamental writings of Toras HaChassidus, it has the power to uplift the human soul from the lowest pits to the loftiest heights The author took upon himself to elucidate the concepts of chassidus using broad, expressive language. Deep and sophisticated ideas became digestible and in this way, fundamental foundations of chassidus became accessible to all. The Tanya is the key to understanding many other chassidic works which were written cryptic manner. These esoteric works-- written in shorthand, and filled with hints and allusions-- were largely abstruse, provided only slight glimpses into ideas which remained more concealed than revealed. (Avodas Avoda, Sichos on Shemos)
