妙法蓮華經玄贊 5.210

5.210

贊曰：下文第四正說三乘喻，有二：初知機，後正說。此初也。「知子先心各有好」者，三乘種姓隨機各別，所宜聞法即是各各為人悉檀。知先心者，是根勝劣，智力及勝解智力之所知也。「知各所好種種珍玩」者，隨其自果諸功德法，即遍趣行智力之所知也。「珍」寶，「玩」弄也好也，戲弄也。有作「翫習耽好」之字，皆非。超出有漏名奇異物，隨得必寶故言樂著。

The Commentary states: The following text is the fourth part: the metaphor of properly expounding the three vehicles. It has two parts: first, knowing the capacities; second, properly expounding. This is the first part. Regarding "knowing that the children's prior inclinations each had what they favored," the lineages of the three vehicles differ according to their capacities; the teaching appropriate for each to hear is the individual-adaptation siddhānta (pratyātma-siddhānta). "Knowing their prior inclinations" refers to the superiority or inferiority of their faculties, which is known by the power of knowing faculties and the power of knowing inclinations. "Knowing what each favored in terms of various rare toys" refers to the dharmas of all the merits of their respective fruits, which is known by the power of knowing the paths leading everywhere. "Rare" means precious; "toy" means to play with, to favor, to amuse oneself with. Some write it with the characters for "practicing and indulging in," but both are incorrect. That which transcends the contaminated is called an "extraordinary object"; whatever is obtained will certainly be treasured, hence it says "attached."
