The Dalai Lama is returning to the Mayo Clinic in Rochester this week. His website said today that the exiled Tibetan spiritual leader will be at the Minnesota medical center for prostate treatment.

The 80-year-old Buddhist holy man is a Mayo regular; most recently he had an annual exam there last September. He then cancelled some appearances when the doctors prescribed rest.

His office says that this treatment will be “followed by a period of rest from the end of January 2016 for approximately one month. His regular engagement schedule will resume in March.”
