Gurdjieff's views were initially promoted through the writings of his pupils. The best known and widely read of these is P. D. Ouspensky's In Search of the Miraculous: Fragments of an Unknown Teaching, which is widely regarded as a crucial introduction to the teaching. Others refer to Gurdjieff's own books as the primary texts. Numerous anecdotal accounts of time spent with Gurdjieff were published by Charles Stanley Nott, Thomas and Olga de Hartmann, Fritz Peters, René Daumal, John G. Bennett, Maurice Nicoll, Margaret Anderson and Louis Pauwels, among others.
