Rumi died in 1273. To this day, his devotees celebrate his departure from the world as one would in a marriage, apt for a man who sought the highest love in life, and found it most completely in death.
Rumi very consciously made himself and his poetry a bridge between cultures and between religions. There is nothing exclusivist about him. He includes everyone in his embrace. He was, and is, a healer of whatever might separate us.
