至於記言書事，各有司存。史誥總稱，謂尼羅蔽荼（唐言清藏），善惡具舉，災祥備著。

The letters of their alphabet were arranged by Brahmâ and their forms have been handed down from the first till now. They are forty-seven in number, and are combined so as to form words according to the object, and according to circumstances (of time or place) : there are other forms (inflexions) used. This alphabet has spread in different directions and formed diverse branches, according to circumstances ; therefore there have been slight modifications in the sounds of the words (spoken language) ; but in its great features there has been no change. Middle India preserves the original character of the language in its integrity. Here the pronunciation is soft and agreeable, and like the language of the Devas. The pronunciation of the words is clear and pure, and fit as a model for all men. The people of the frontiers have contracted several erroneous modes of pronunciation; for according to the licentious habits of the people, so also will be the corrupt nature of their language. With respect to the records of events, each province has its own official for preserving them in writing. The record of these events in their full character is called Ni-lo-pi-ch'a (Nilapita, blue deposit). In these records are mentioned good and evil events, with calamities and fortunate occurrences. To educate and encourage the young, they are first taught (led) to study the book of twelve chapters (Siddhavastu).
