Although Wenling Jiehuan’s (溫陵戒環, ?–1182 or 83 ) commentary Lengyan-jing Yaojie (楞嚴經要解) greatly influenced later generations, research on the commentary is scarce. Qian Qianyi (錢謙益, 1582–1664) mentioned that the commentary is closely related to Changshui Zixuan’s (長水子璿, 965–1038) Shoulengyan Yishuzhujing (首楞嚴義疏注經). To elucidate the Yaojie’s features and validate Qian Qianyi’s remarks, this paper investigated references to other Sūtras or documents, as well as other sources that Jiehuan might have referred to, focusing on the relationship between the Yaojie and the Yishuzhujing. The results shows that Qian Qianyi’s opinion has some validity.
