Internationally renowned Qi Gong Grandmaster Sikung Lowe, a 53-year-old Qi Gong practitioner, medical intuitive and healer, has been invited to hold a presentation on Qi Gong Feb. 15 at the University of Colorado at Boulder's Eaton Humanities Building from noon to 1:30 p.m. The introductory meeting is free and open to the public.
