In this study, we looked at Chinese Siddhavastu around the 11th century. This is to examine the aspect of Siddhavastu for a period more than 200 years after Zhiguang's Xitan ziji, which was written around 800 years ago. The seven-volume Keiyū India's Syllabary source, written in 1035, has many parts that are similar in format to the Xitan ziji, but compared to the Xitan ziji, it does not have as many commentaries, and overall, it is composed of content that shows actual examples of generalized Siddhavastu. Representative examples include the 34 syllables that do not appear in the Xitan ziji and the combination of ña and ṇa, the ‘訖里(kṛ)章’ that appears in the Xitan ziji does not appear in the Keiyū India's Syllabary source, in particular, it is not mentioned at all in the Xitan ziji, but in most scriptures, only the basic meanings of the 12 declension vowels and 34 consonants are shown, whereas in the Keiyū India's Syllabary source, the meanings of all letters created by combining the 12 declension vowels and 34 consonants are explained in an entire volume. furthermore, by explaining the combination of the 12 declension vowels and 34 consonants through examples across four volumes, if the Xitan ziji is a basic textbook for those encountering Sanskrit for the first time, the Keiyū India's Syllabary source can be said to be a representative practical book on Sanskrit that was in common use until then.
