維摩經玄疏 1.41

1.41

四、相似即者，如鐵輪十信，雖是肉眼，名為佛眼。《法華經》說「六根清淨之相」是也，此即柔順忍位，名相似即也。

Fourth, as for identity in resemblance: like the ten faiths of the iron wheel, although it is a fleshly eye, it is called the buddha-eye. This is what the Lotus Sūtra describes as 'the marks of the purity of the six sense faculties'; this is the position of compliant forbearance, called identity in resemblance.
