Related to "mind-liberation and wisdom-liberation." This chapter discusses the problems of the "wisdom-liberation explicitly," responds to the shortcomings of previous studies, and puts forward the true meaning of "wisdom-liberation" in "Nik¿ya." The first section mainly sorts out and solves the related problems of the "wisdom-liberation," leading to the deviation of the research tendency of the liberation of knowledge more than the Susima sutta. Texting the content mentioned in the Sutra and comparing the "Susima sutta" in the "Nik¿ya" and "Agama Sutra," I find that there are some differences, and the description of the "wisdom-liberation" in the Sutra is not very clear. In the second section, the four Jhanas, the five lower fetters, Seven Sam¿patti, Eight-liberation etc., are directly related to the "mind-liberation and wisdom-liberation." The discussion of the "mind-liberation." According to "Nik¿ya," many Sutras records the "mind-liberation" of them alone. They are of various kinds, so it is necessary to sort them out for further understanding and discussion so that the study of the "wisdom-liberation" will not be confused. There are four kinds of mind-liberation: "Infinite Mind-liberation," "Benevolence Liberation," "Big Mind-liberation," "Right Mind-liberation," "Unmotivated Liberation," "Non-holding Liberation," and so on. Among them, the practice method of "mind-liberation" is the most detailed. Although the name of other liberation is different, most of them take "mind-liberation" as the practice method. Here I also want to respond to one thing, the "mind-liberation" itself is a method of spiritual practice liberation; why to want to drive it out of the door, let alone the "Wisdom-liberation" is inseparable from the "Mind-liberation. " If the two appear together in the sutras, they have a special meaning in themselves, so we can't ignore them at will. Suppose we discuss the wisdom-liberation apart from the "mind-liberation. " In that case, there are only about eight sutras in "Nik¿ya." And all the other sutras of "wisdom-liberation" have records of the transition. From the four Jhanas to the "wisdom-liberation " except the"Susima sutta." Therefore, modern scholars try to find a more content basis for the "wisdom-liberation" from Pali's "Nik¿ya" explanatory books." This paper mainly studies the relationship between "mind-liberation, wisdom-liberation," and how to enter such a state of liberation based on the Sutra of "Nik¿ya" and Agama Sutra.
