“Sadness is but a wall between two gardens.” Khalil Gibran
How appropriate! The garden of good and evil*. Between the Earth and the Heavens. I suspect that until one chooses the garden of good and so lives in the garden of evil there is a constant longing for finally entering the other garden and arriving ‘home’. Until then, it but a lot of sadness, the sadness of longing and not having.
