All those Great Saintly Masters
Who knew the deep desires
Of the gods, men, and other living beings
Of all the worlds,
Revealed the Highest Truth [Prime Meaning]

li is originally of the unspeakable [nature]. He has borrowed words to speak about it. They are called [expedient] devices (upāya). Again, the two vehicles are employed as [teaching] aids for transforming them (beings). They are called other [expedient] devices. The One Vehicle is so deep that it has to rely on them to be manifested. According to one theory, what was preached [by the Buddha] for forty-nine years belong to expedient devices. The subject of the present preaching, the Dharma Blossom (or Lotus), belongs to “other [expedient] devices.”
