Sefer HaBahirספר הבהיר
Posquières (Provence) · 1175
"The Book of Brightness." The first text we'd recognize as kabbalistic in form. Circulated in 12th-century Provence and Spain (attributed to the talmudic sage R. Nehunia ben HaKanah but composed centuries later), the Bahir introduces the language of the sefirot as a description of the divine inner life. It set the stage for the Zohar a century later.
