The text of the Sefer Yetsirah presented here follows the “experimental exercise” produced by A. Peter Hayman in his Sefer Yeṣira: Edition Translation and Text-Critical Commentary, “Appendix III: The Earliest Recoverable Text of Sefer Yesira” (Mohr Siebeck, 2004). For details on his construction and his review of the available recensions of Sefer Yetsirah, please refer to Hayman’s complete commentary. Numbers in parentheses indicate sections. I have added spaces between sections indicate traditional chapter breaks. Square brackets indicate some doubt as to whether the included wording was present in the earlier form of the text (p.124). . . .
