The idea of this research approach is to use doctrine and literary as two directions, to deeply study the KaruNApuNDarIka-sUtra. Based on the research,the conclusion of the studies is stated as follows: From the side of doctrine : The dharmacakra-pravartana of the KaruNApuNDarIka-sUtra is not limited to darma-giving; besides,its important goal is to lineage.The dhAraNI is not only the skill of memory, but also the summary of Buddhism ; and vital method for Buddha to rotate the dharmacakra .The meaning of ” dharmacakra-pravartana” and”dhAraNI”in the KaruNApuNDarIka-sUtra, the meanings are broaden and deepened. The KaruNApuNDarIka-sUtra elaborates on both pure buddhalands and impure buddhalands. According to the contents of scripture, it explores the environment , the living beings and teaching methods on pure buddhalands and impure buddhalands. With regard to characteristics of living beings, they in the KaruNApuNDarIka-sUtra are bodhisattvas, the major teaching method is naturally mahayana, because the living beings on impure buddhalands have various besetments, three fold vehicles is applied to teach those beings in accordance with their characteristic。 From the side of literary character:First of all, treat the elementary construction of the KaruNApuNDarIka-sUtra. Wakyamuni Buddha once stayed on Mt.GrdhrakUTa in RAjagRha, many bodhisattvas look towards the southern-east direction and clasp their hands together, which leads Ratnavairocana Bodhisattva to raise questions, so another space is introduced– the PadmA Buddhaland;stimulated by the display of scenes of each pure buddhalands, Wantimati Bodhisattva asks Wakyamuni Buddha”What is the reason that you have not taken apure buddhaland? ”, so Buddha’s JAtaka in this space is illustrated, starting from SamudrareNu.Subsequently, probe into the characters of people in KaruNApuNDarIka-sUtras. With SamudrareNu as center, spread out the network of people relationship, including both ethical relation and religious relation.How to categorize the types of people is based on their position and influence level in the KaruNApuNDarIka-sUtra, separate people into major personage and secondary personage.Lastly, through 8 JAtakas of MahAsattvas Budhisattvas, propagate the great compassion on why Wakyamuni Buddha becomes Buddha in this impure buddhalands, and confer the meaning of culture behind the stories.
