Everyone is Schizophrenic. Only the Awakened one is fully free of all divisions. All schizophrenia originates from the projections of ones mind onto the outside. People go on projecting themselves onto some god, guru, avatar or parental authority. The moment their projections become conscious society labels these individuals with one of any number of social disorders. But really all schizophrenia is good. At least when It becomes conscious, when It surfaces.
It is revealing something very deep. The Schizophrenic is on the edge of his mind. One more step and He/She can enter into what Zen calls no-mind, nothingness, the beyond.
