I have a friend who asked me to help her find any information on yoga, and it is wrong for her to practice its exercise. She herself is a faithful sacramental Catholic who enjoys and does yoga every now and then. Just recently she was handed a Christian book that downgraded yoga, and explained why Christian should have no part of it. The book she was given was not Catholic, so she is interested in finding a book that is Catholic and to see what the Church might have to say about it.
Thanks and God bless.
