“The Five Parts of the Dharma Realm”: Preliminary Remarks on the Collection of the sems phyogs Texts in the Tangut Translation research-article Kirill J. Solonin (Солонин Кирилл), Yu Xiaogang (曉剛 喻) Central Asiatic Journal, Volume 63 (2020), Issue 1-2, Page 173 - 190 The paper discusses the recently identified collection of sems sde class texts in Tangut translation. The author provides initial textual analysis of the texts in the composition and offers several suggestions concerning the historical setting of these texts. There is also evidence allowing to suggest that several versions of the “five early translations”, probably based on varying Tibetan versions, were current in the Tangut State. The study revealed a systematic relationship which existed between the compositions united under the sems sde category in the Tangut State. They formed a coherent whole of core texts, commentaries and historical accounts. Finally, several observations concerning possible historical traditions of the Tangut sems sde are provided.
