While I was in New York recently, I had a meeting with Kabir Helminski, Shaikh of the Mevlevi Order of Sufism.
From Wikipedia: Kabir Helminski is the Co-Director of the Threshold Society, a non-profit educational foundation that has developed programs that provide a structure for practice and study within Sufism and spiritual psychology. He has translated many volumes of Sufi literature, including many works of Rumi, and is the author of two books on Sufism: Living Presence and The Knowing Heart.
For more than twenty years, Mr. Helminski’s focus has been developing and sharing a contemporary approach to Islamic concepts and practice, both within the Islamic community and outside of it. In 2001 he was the first Muslim to deliver the prestigious Harold M. Wit Lectures on Spirituality in Contemporary Life at Harvard Divinity School. His lectures are to be published as a book by The Paulist Press.
He is one of the signatories of A Common Word between Us and You, an open letter by Islamic scholars to Christian leaders, calling for peace and understanding.
