妙法蓮華經玄義 1.215

1.215

「妙法蓮華」名異眾典，別也；俱稱為經，通也。立此二名，凡約三意，謂教、行、理。從緣故教別，從說故教通；從能契故行別，從所契故行通；理從名故別，名從理故通。略說竟。

The name "*Saddharma-puṇḍarīka*" differs from other scriptures: this is specific. Both being called "sūtra": this is general. Establishing these two names generally involves three meanings, namely: doctrine, practice, and principle. In terms of conditions, doctrine is specific; in terms of the preaching, doctrine is general. In terms of that which realizes, practice is specific; in terms of that which is realized, practice is general. In terms of names, principle is specific; in terms of principle, names are general. The brief explanation is finished.
