The transit of the Middle Passage occurs in the fearsome clash between the acquired personality and the demands of the Self. A person going through such an experience will often panic and say, 'I don't know who I am anymore.'
Hollis defines the Middle Passage as the core Jungian individuation crisis in which the socially constructed personality is violently displaced by the deeper demands of the Self, producing existential disorientation as a necessary prelude to renewal.
