佛遺教經論疏節要 1.358

1.358

此三深廣，沒溺眾生，故如海也。聞法起信，如得牢船，必假思慧為帆檣便風，方有所利。苟無此二，船雖堅牢，但在此岸。

These three are deep and vast, drowning sentient beings, and thus are like an ocean. Hearing the Dharma and giving rise to faith is like obtaining a sturdy boat; but it must rely on the wisdom of reflection as its mast and sail and favorable winds before it can bring benefit. If it lacks these two, even though the boat is sturdy, it will merely remain on this shore.
