妙法蓮華經玄義 10.190

10.190

菩薩藏中有能頓悟者，如《華嚴》等經所為眾生，不由小來，一往入大，故名為頓。從漸入者，即向退菩提心聲聞，後能入大，大從小來，故稱為漸。雖有頓漸不同，然受大處一，故對此二人所說為菩薩藏也。

Among those in the bodhisattva-piṭaka, there are those who can awaken suddenly: like the sentient beings for whom sūtras such as the Avataṃsaka were spoken, they do not come by way of the small, but enter the great straightaway; hence it is called 'sudden.' Those who enter gradually are the aforementioned śrāvakas who regressed from the bodhi-mind and are later able to enter the great; since the great comes from the small, it is called 'gradual.' Although there is the difference of sudden and gradual, their locus of receiving the great is one; hence what was spoken for these two persons is the bodhisattva-piṭaka.
