The school and the Tibetan Association of Colorado say the Office of Tibet in Washington, D.C., announced the cancellations Friday. He had been scheduled to appear there Oct. 20.
Officials said the office of Tibet, which represents the Dalai Lama in North America, said doctors advised the 80-year-old holy leader to rest and that he would return to India.
A secretary to the Dalai Lama, Chime Rigzin, told The Associated Press on Thursday that the Dalai Lama had been to Mayo Clinic for a "routine annual health checkup" and had no health complaints.
