Sepher Yetzirah (Book of Formation)

The Sepher Yetzirah is a primary Kabbalistic text of unknown authorship and disputed date, traditionally attributed to Abraham but actually the product of an anonymous and layered composition history that this record does not resolve. As a primary text it is authoritative for what it itself states about creation through the thirty-two paths of wisdom, the ten sephiroth and the twenty-two Hebrew letters, checkable directly against the text, not for a settled account of when or by whom it was actually composed, which remains disputed among scholars of Kabbalah. Use it to establish what this foundational text itself teaches about the sephirot and the letters; a claim about the text's own documented composition history or about a later Kabbalistic school's specific elaboration of it needs a dedicated scholarly source.
