Bede Griffiths describes this profounder sort of dialogue, what I call existential dialogue: "The primary purpose of inter-religious dialogue is mutual understanding, but this means understanding the other religion from within, that is, by sharing the other person's experience of his religion. This comes about not only through shared conversation but also through sharing in religious ritual and prayer together." Existential dialogue is this inner openness to the other in mutual trust, respect and sympathy. But existential convergence goes even deeper.
