The reason why Buddhist scriptures were not written in vernacular was that these scriptures had been passed down and explained for a long time in Buddhist heritage. They contained the teachings, doctrines, precepts, and cultivation methods of Buddha. For beginners, understanding these scriptures required a certain background and knowledge. Using vernacular might make it difficult for readers to understand the important concepts and terms in the classics, and they might not be able to fully understand the profound philosophical thoughts contained in the classics. Therefore, Buddhist scriptures are usually written in classical Chinese or Sanskrit so that only people with a corresponding Buddhist background can understand them. Learning Buddhist scriptures requires a certain amount of Buddhist knowledge and background. Only on the basis of in-depth understanding can one better understand the teachings and cultivation methods in the scriptures.
