Sefer Yetzirahספר יצירה

Jerusalem · 500

The proto-text of Jewish mysticism. A short, dense work attributed traditionally to Abraham and dated by scholars to somewhere between the 2nd century BCE and the early Geonic period. It describes the creation of the world through ten primordial numbers (sefirot) and twenty-two letters of the Hebrew alphabet — the architecture every later kabbalistic system would build on.
