“The Holy Epistle” of Ba'al Shem Tov is one of the signature texts of the founder of Hasidism. Hasidism originated in the late eighteenth century and soon developed into a particularly rich movement of spiritual awakening within Judaism. It has adherents to this day. The founder, whose title literally means “master of the good [holy] name,” was also known as the Besht (derived from a shortening of the title Ba'al Shem Tov) or simply as Ba'al Shem. In light of the fact that the vast majority of our knowledge of the movement's first teacher and exemplary saint is at second hand, the modern significance of “The Holy Epistle” to no small degree lies in its authenticity. This lack of firsthand documents stems from the nature of Hasidism at the time of its inception, wherein many of the homilies, discourses, and other manner of teachings were the responsibility of a charismatic teacher's disciples to document and possibly publish. Since the stories surrounding the founder of the movement are especially rich and couched in legend, not to mention stylistically drawn from earlier Jewish hagiographies, Ba'al Shem Tov almost disappears from sight as a genuine person. For a time in the second half of the nineteenth century some historians of the movement doubted that he had even actually existed.
