This book is a reworking of an earlier work The Ganesa Purana. Volume One . Upasanakhanda, Otto Harrassowitz, Wiesbaden, 1995. I have revised the translation for this new edition, the Introduction has been substantially shortened and the notes to the translation have been severely truncated. I have tried to make the translation less literal than in the previous volume and I have been able to correct some mistakes in the initial translation, especially following some good suggestions made by reviewers such as Ludo Rocher and John Brockington.
