For the last 10 years Anna Ngabayena has been haunted by her past. The memories of the violence she encountered as a foot soldier in the African National Congress (ANC) struggle against apartheid have plagued both her dreams and waking life. In recent weeks things had begun to change, said Ngabayena, now 42 years old. She had just taken part in a unique rehabilitation programme run by the National Peace Accord Trust (NPAT), which uses the natural environment as a means of coming to terms with a turbulent past.
