Any proving requires dedication and hard work and Dreaming Potency was no exception. My grateful thanks go first to Nelson and Muriel Ngqase of Mandela Township outside Cape Town for their inspiration and for their prescription for my dream which led to the proving.
There are no telephones or post boxes in Mandela Township and I am grateful to Dr Renee Usdin for introducing me to the sangomas in the first place and enabling continuing communication with them.
The greatest part of the work is of course carried out by the provers and supervisors. I would like to thank them all, especially my supervisors, Sophie Dutordoir, Helen Guillam, Alan Harvey, Judy Mistral, Richard Napper and Penny Stirling, not only for their hard work but also for their companionship on the journey upon which we embarked.
Last but not least I am very grateful to Peter Fraser for his encouragement and patience and skill in bringing about order and coherence whilst maintaining the spirit and meaning of the proving.
