Nelson Mandela Foundation

The Dalai Lama said Friday in a letter sent to the family of Nelson Mandela that he would miss a "dear friend" who he hailed as "a man of courage, principle and unquestionable integrity".

In a statement on his website, the exiled Tibetan spiritual leader said that "the best tribute we can pay to him is to do whatever we can to contribute to honouring the oneness of humanity and working for peace and reconciliation as he did".
