The present book is the fruit of these initiatives. The recording, transcription and translation of the material published here was a process of dialogue between generations, in which the young and old cooperated to attain a common goal: to understand and transmit the stories inherited from their ancestors. The elders shared their knowledge with generosity, even though they were sometimes in delicate states of health, thereby demonstrating their firm commitment to the objectives of this publication. The tireless work of the Urarina teachers, who are more familiar with the standardised orthography of their language, furnished the project with transcriptions and translations, so that the cultural treasure this book contains can be shared with others throughout Peru and the world.
