| The unearthed sites of Tangut Mahaprajnaparamita Sutra are concentrated in khara-khoto,but there are also sporadic excavations in the northern grottoe of Dunhuang and other places.In this paper,the author interprets the volume 47 of Tangut Mahaprajnaparamita Sutra,and gives notes on the differences between Tangut and Han,and the Buddhist names and so on.Volume 47 of Mahaprajnaparamita Sutra has a large number of homonymous compound words,personal echo and phonological conversion.In the summary of phonological conversion,it is found that the rules of phonological conversion are no longer important,and the basic form can be used with derivative forms.These phonological phenomena in volume 47 help us to understand the Tangut grammar in depth.A large number of Buddhist scriptures in Chinese have also been unearthed in the Dunhuang Sutra Cave.Comparing the 47 volumes of the Mahaprajnaparamita Sutra unearthed in Dunhuang with them,and combining with the catalogue of Buddhist scriptures unearthed in Dunhuang and the existing historical data,we can clearly understand that the introduction of the Mahaprajnaparamita Sutra in Chinese into the Xixia Dynasty is not only a way of the Song Dynasty,The Buddhist scriptures left by Hexi region are also an important part of the Xixia Chinese Buddhist scriptures.In addition,regimes such as the Liao and Jin dynasties have always had Buddhist exchanges with the Xixia Dynasty.As for the voluminous number of Mahaprajnaparamita Sutra,this paper points out that some voluminous numbers of Mahaprajnaparamita Sutra included in the khara-khoto Literature in Russia are inconsistent.At the same time,based on the previous research,The Chinese version of Mahaprajnaparamita Sutra uses Thousand-Character Classic,while the Xixia version of Mahaprajnaparamita Sutra uses a four character sentence created by its own ethnic group as the number,and has its own unique number system.The Xixia people display their own ethnic viewpoint on the origin of the universe in the form of the Xixia number,and the idea of heaven and earth worship is reflected in many existing Xixia books.it can be found that the voluminous number of Mahaprajnaparamita Sutra in Xixia is likely to be influenced by the Thousand Character Text in Chinese.The unique voluminous number contained in the Xixia version of Mahaprajnaparamita Sutra contains both the Xixia myth and the concept of the creation of the universe,which are deeply influenced by the culture of the Central Plains.Xixia myth of the creation of heaven and earth and the spawning myth are even more influenced by the Central Plains. |
