In the 1960, Fr. Gaspar Koelman, a Jesuit working in India, did a meticulous study of Patanjali, The Patanjala Yoga, that is invaluable even today. From a very different angle, in 1990 Ravi Ravindra, a Hindu scholar, published an insightful interpretation of the Gospel according to John entitled The Yoga of the Christ. And — lest we forget — there have been many columns, essays, and letters by Christian leaders cautioning Christians against being enchanted by physical practices that ultimately mean a whole way of life — possibly or probably incompatible with Christian values. So the fruits of my seminar — this latest “Jesuit Yoga” — need to be carefully assessed, for the sake of the general question, How can we benefit from the ancient and wise tradition of yoga, as Christians? My hope is to add at least two more to this series of reflections — Jesuit Yoga II and III — to spell out a bit more of what I mean. I also very much welcome comments from readers who (for better or worse) have brought yoga together with Christian (and/or Ignatian) spirituality.
