妙法蓮華經玄贊 10.110

10.110

贊曰：第六勝果遂生。有三：一聞法能持，二六根清淨，三增壽說法。若常不輕不先披讀像法之中法華經者，豈於臨終聞即能持？先不修因，果如何起。已前禮拜是四十心位，聞法根淨四善根位。增壽命故得大善寂，漸為理觀觀真理故。

The Commentary says: Sixth, superior fruition consequently arising. There are three parts: first, hearing the Dharma and being able to uphold it; second, purification of the six sense faculties; third, increasing lifespan and preaching the Dharma. If Sadāparibhūta had not previously opened and read the Lotus Sūtra during the Semblance Dharma age, how could he have been able to uphold it upon hearing it at the end of his life? If one did not cultivate the cause beforehand, how could the fruition arise? The homage prior to this belongs to the stages of the forty minds; hearing the Dharma and faculty purification belong to the stage of the four roots of goodness. Because his lifespan was prolonged, he attained great and good tranquility, gradually engaging in contemplation of principle to observe the true reality.
