Dwight Goddard collected a sample of Buddhist scriptures, with the emphasis on Zen—along with other classics of Eastern philosophy, such as the Tao Te Ching—into his Buddhist Bible in the 1920s. More recently, Dr. Babasaheb Ambedkar attempted to create a single, combined document of Buddhist principles with his “The Buddha and His Dhamma”. Other such efforts have persisted to the present day, but currently there is no single text widely accepted as being central to all Buddhist traditions.
