瑜伽論記 23.25

23.25

第六解四怖，景師釋云：由四因緣，於二處所發生恐怖，能為障礙者：一、於有為諸行生怖，二、於涅槃生怖，由生怖畏，於其聖教及以涅槃不生受樂，名為障礙。

Sixth, in explaining the four terrors: Master Jing's commentary states: '"Due to four causes and conditions, terror arises toward two loci, which can act as obstacles": first, terror arises toward conditioned formations; second, terror arises toward nirvāṇa. Because fear and terror arise, one does not give rise to acceptance and joy toward the holy teaching and toward nirvāṇa; this is called "acting as obstacles."'
