Crossing the Red Sea doesn't lead to the Promised Land directly. It leads first to the wilderness, and then to the encounter with the numinosum. Only after that does it lead to the Promised Land.
Edinger articulates the Red Sea crossing as a three-stage individuation schema: dissolution of the old orientation, encounter with the numinosum in the wilderness, and arrival at a new level of consciousness.
