Meister Eckhart
Meister Eckhart (1260–1328) was a priest, a mystic, and nearly a heretic (he died before the Church court’s verdict). In the 20th century, the Roman Catholic Church rehabilitated him and the late Pope John Paul II spoke of his work with fondness.
However, what makes him of particular interest is the fact that he has influenced a wide range of spiritual teachers and mystics both inside and outside the Christian tradition. Erich Fromm, Eckhart Tolle, Richard Rohr, D. T. Suzuki, and Rudolf Steiner have all credited Eckhart as being an important influence on their thought. In addition, his work has influenced the development of 20th century American Buddhism and the Theosophical tradition.
Eckhart wrote at a time―much like our own―when society appeared to be coming apart at the seams. In the midst of all that chaos and uncertainty, he captured the many forms and stages of the love of God, the mystic path, and the journey of transformation―in language so startling that he, too, was often accused of heresy.
