Five guided meditations here from Dr Craig Hassed, a member of the OMS team and one of the presenters at the recent UK retreat. Some other useful downloads too - Craig's podcasts are at the end. Interesting that the University of Auckland Medical School in New Zealand recognises the value of mindfulness for good health and well being.
