A symbolic figure in
Kabbalism (A
esoteric sect of
Judaism centring around
mystical interpretations of the
"Torah") representing in essence a 3-dimensional image of the
spiritual realm in the form of a
diagram. This same diagram is also drawn in
Gendou Ikari's office. The figure is comprised of ten
spheres linked by 22
paths, and shows the route for
humans to attain the highest possible
spiritual level. It is said that this figure can be interpreted in various ways: as a step-by-step diagram for
meditation, a map leading to
wisdom, or a prediction of
humankind's
future, etc. In episode 26'
"Magokoro wo, kimi ni", the
Eva series form a giant
Tree of
Sephiroth in the
sky.
