A sharp blade was needed. In the dream I could not get the blade sharp enough. The dreamer needed a better contact with the Logos-Cutter than he had as yet achieved.
Edinger identifies the blade as the psychic instrument of separatio and the Logos-Cutter, whose insufficient sharpness in a dream signals the dreamer’s inadequate capacity for differentiation and conscious discrimination.
