This paper researches Renshan Jizhen's 仁山寂震 (1631-1697) Da-Bo-Re-Chan-Fa 大般若懺法. Regarding academic discussions on Yuka or Sutra chanting assemblies in the Ming and Qing Dynasties, this paper shifts focus from secular aspects, such as praying for blessings and bringing peace to the dead, praying for the nation, to the relationship between repentance and Chan practice. As well as the newly discovered scripture Hanyue Fazang's 漢月法藏(1573-1635) Master Sanfeng Hanyue's Mind Repentance Ritual 三峰和尚心懺, the Da-Bo-Re-Chan-Fa is a rare and precious scripture for studying the Sanfeng Lineage's repentance ritual. The main findings of this paper are as follows: First, Da-Bo-Re-Chan-Fa's function of assisting Chan practice can be verified by comparing it with other crucial scriptures, clarifying that the Sanfeng Lineage's repentance scripture can be used in the ritual to offer prayers for peace and eliminate disasters, used as upāya for eliminating obstructions before chan practice, and assist meditators in manifesting their Buddha nature. Second, preliminary studies have shown no specific practice of repentance in the Southern School of Chan. However, Da-Bo-Re-Chan-Fa, a repentance scripture written by Jizhen, Chan master of Linji School, provides an example of the practice of repentance in terms of ultimate truth and practice. Third, Da-Bo-Re-Chan-Fa integrates Pure Land thoughts and the essentials of the Linji School's practice of "One Thought in Present" in the rites of repentance. Thus, the scripture is crucial for verifying the relationship between Chan and Pure Land in Linji School in the early Qing Dynasty.
