Hekhalot Zutartiהיכלות זוטרתי

"The Lesser Palaces": older, rawer, more magical — organized around Rabbi Akiva (the one who entered Pardes in peace and left in peace) and the names he brought back. Less liturgy, more technique: the Name as vehicle, glossolalic strings of vowels and seals, instructions guarded by warnings. The closest thing in the corpus to a working grimoire of ascent.
