The sutta discusses two main topics: the elaboration of the Ten Precepts (Cula-sila), the Middle Precepts (Majjhima-sila), and the Great Precepts (Maha-sila). Cula-sila deals with the Ten Precepts to be practised by devout buddhists, while Majjhima-sila gives a detailed description of the practice of the sixth, seventh, eighth, and ninth precepts, together with the practise of plant conservation and speech etiquette.
