or Merkava
Throne or chariot of God, as described by Ezekiel .
It became an object of visionary contemplation for Jewish mystics in Palestine in the 1st century AD; in the 7th–11th century, Merkabah mysticism was centered in Babylonia . Merkabah mystics courted ecstatic visions that involved a dangerous ascent through celestial hierarchies to the throne of God. Hostile angels guarded the gates to the seven "heavenly dwellings," and a successful journey required magical formulas. The Talmud warns that of four men who engaged in Merkabah, only one had a true vision; of the others, one died, one went mad, and one became an apostate.
