The minuscule composition known as Sefer Yesira (SY), so tiny some thought it to be meant as an amulet, is a challenging text, begging for commentary. Though the Hebrew text is very short (about 1,000 words), it has played an important role in Jewish thought, and in more recent times, in the academic study of Jewish thought. The “book” itself contains very little prose; it consists mostly of catalogs of the components of the cosmos, in groups of two (pairs of opposites), three, and seven, and their sums—10, 12, 22, and 32. The cataloged components are those making up the physical universe, the human body, and time. The 22 letters of the Hebrew alphabet are very significant as well and are matched to the other components of the universe. The original intent of the author or authors is not known.Sefer Yetsira is indeed a mysterious text, more so even than is indicated in this article. There is no agreement on its original date of composition or what the original text looked like. Some years ago I comment briefly on it and gave some bibliography here. It is foundational to the mystical traditions of Kabbalah and the Zohar, whether or not it is itself a mystical text.
A book of this sort cannot be understood without commentary, and SY has been interpreted in very different ways. Some claim that it was originally meant to be a work of mystical magic, but this reading is clearly prejudiced by the kabbalistic appropriation of the text, a process which began in the 12th century, and, even more so, by a fierce turf defense by academic specialists in the Kabbalah.
I do not know if at it is at all possible to assert anything about the original authorial intent behind the text. One can, however, speak with a great deal of certainty about the way the first interpreters of SY read the book. We possess extensive commentaries, in Judaeo-Arabic and in Hebrew, written by individuals throughout the Jewish diaspora in the early medieval period. Some are famous, others are familiar mainly to specialists. Each of the following glossed Sefer Yesira, reading it as a book of science: ...
