Let's compare the lives and teachings of three of the world's most admired spiritual masters: Francis of Assisi, the Christian saint; Dogen, the great Zen Buddhist teacher; and Rumi, the Islamic Sufi master. They lived during the same turbulent century. They integrated mystical experiences of the sacred into their lives, and they can inspire us to do the same. An interfaith approach to spiritual exploration, one that links Christian, Buddhist, and Islamic mystical teachings within a vibrant historical context and shows how they not only complement each other but remain profoundly relevant in the twenty-first century. Our conversation interweaves the spiritual lives of these Christian, Buddhist, and Muslim teachers.
