OuyiZhixu (1599－1655) uses Buddhism to interpret Confucianism because that Confucianism is the mundane world view centers around Benevolence. Human being has its own Benevolence which represents ones real temperament, real life and contains inner morality. Buddhism is the supra-mundane world view, is seeking of truth, and speaks up for the path of Bodhisattva to Buddhahood. Truth will certainly manifest itself in the mundane world view. Hence the practicing of Buddhism and Confucianism both theoretically based on common point. That is why QuyiZhixu is the bridge builder of intercommunication between Confucianism and Buddhism. OuyiZhixu has fundamental learning of Confucianism and Buddhism. In addition to that he seeks truthful explanation of Essential nature and Characteristic upon practicing and variously studies all doctrines of different sects. Later his writings were mixed with Tien Tai's theory because he was deeply influenced by Tien Tai Sect on his learning course. For instance, Amitabha Sutra Yao Jie was composed when OuyiZhixu was 49 years old. Among three Pure Land's sutras, he pays much attention to Amitabha Sutra. For this reason, the Amitabha Sutra Yao Jie is the most important writing under his Pure Land theory. In Amitabha Sutra Yao Jie, OuyiZhixu interpreted Pure Land theory by the Tien Tai's thought. Firstly, he illustrated the Amitabha Sutra with Tien Tai's Five heavy-profound- meanings.

These three endowments are correlated. Faith, there are six kind of faith, self-faith, faith-other, faith-course, faith-effect, faith-matter, and faith-reality. Vow, there are two teachings of vow, disliking and detaching Saha Land then seeking after with pleasure of the Ultimate Bliss, and making a vow that contains Faith and Vow. Practice, it is chanting Buddha's name, or is chanting particular name, is a simple and easy short-cut. The most easy practicing methods have that it can be achieved immediately and completely, can be popularized through all three categorized groups of sentient beings, can be taught either sharp or dull group, and can be spread all over to whomever get it. This easy practicing method contains two fields, the Three Kind of Wisdom and Mindfulness Chanting Buddha under a high level of meditative concentration.
