MINNEAPOLIS — The Dalai Lama is assuring his followers that he is in good health, despite receiving treatment in the U.S. for a prostate condition.

The 80-year-old Tibetan Buddhist leader spoke to about 3,000 people Sunday at the Minneapolis Convention Center.

The Dalai Lama arrived last month at Mayo Clinic in Rochester, Minnesota. The Star Tribune reports he told the crowd he’d been receiving treatment for prostate problems.
