In the “Shobogenzo hokketenhokke” (正法眼蔵,法華転法華) we find the expression “yokuryo shujo kai ji go nyu” (欲令衆生,開示悟入). It have been thought that Dogen (道元) quotes this expression from the “Hokekyo hobenbon” (法華経方便品). However, I wondered about this, and investigated a number of sources. As a result, I believe that Dogen (道元) quoted this expression from the Shoulengyan yishuzhu jing (首楞厳義疏注経) of Zixuan (子〓).
