Sefer Yesira is one of the foundational texts of Jewish Kabbalah whose cryptic pronouncements encapsulate the twenty-two elemental Hebrew letters and ten enumerations whose combinations and permutations purport to constitute the bedrock of all worlds, experiences, and languages.

Sefer Yesira can be likened in effect to a Hebrew Oblique Strategies of Brian Eno fame, providing a powerful prompt for creativity. Sefer Yesira’s public appearance during the 10th century instigated an incredible variety of Jewish commentaries, the influence of which spread further afield into Western Culture during the Renaissance in Italy and has reverberated even unto our time. In this spirit, I have entitled my translation of Sefer Yesira as the 'Book of Creativity'.
