While I have other fish to fry, I am interested in a postgrad certificate course in religious mysticism. Since it is an interest course only, the accreditation aspect is not so important. Obviously, I would prefer institutions that produce a meaningful education. A comparative approach would be good, however, I am particularly interested in the Christian Mystics and their teachings. I would be interested to hear what is available by distance learning.
Try the University of Wales Lampeter. They have a variety of offerings that should appeal. http://www.lampeter.ac.uk/trs/Postgraduate/prospective_taught/taught_degrees.htm
