The higher mind recalls a person to the early ardor of the soul, before the outer life had thickened and grown crowded. Jerusalem is the center of consciousness, the seat of vision within, and it is being reminded of a first devotion, the kindness of youth when the soul followed spirit through the empty places without hesitation. The wilderness and the unsown land are the state before habits and worldly cultivation set in, a bare inner ground where the whole attention was turned toward the higher and nothing else was yet planted. That first love was the soul married to spirit before the accumulations of the outer world came between them.
Spirit remembers when a person's attention was undivided and freshly given, and calls the consciousness back to that early, uncluttered devotion.
Jerusalem: the center of consciousness in a person, the seat of vision addressed and called to remember
The wilderness: the bare inner state before habits and worldly cultivation set in, where attention was wholly turned toward spirit
The land that was not sown: the unplanted ground of the soul before the accumulations of outer life took root
