妙法蓮華經玄贊 4.246

4.246

贊曰：此釋所由，及結歸真實，以不定人創在凡夫，小智樂小無欣大意，不信自作佛，故初說三乘；雖復初權，後必真實，但化菩薩。

Eulogy: This explains the reason and concludes with the return to the real: because those of indeterminate lineage are initially ordinary beings, with inferior wisdom they delight in the lesser and have no aspiration for the great, not believing that they themselves will become buddhas, he initially preached the three vehicles. Although the beginning is provisional, the end is certainly real, transforming only bodhisattvas.
