Ego

Something of the soul is in the ego.
The soul reaches individuation
through the experiences of the ego.
The ego is an outpost of the soul,
feeling its way into and responding to the "social sphere"
and the mental patterns of this sphere.

The ego is only a scaffolding needed
to frame and simplify the work
of making fully concrete and substantial
the field of the soul's activities
