天台八教大意 1.8

1.8

The remaining six teachings are present throughout the gradual and the sudden. Hearing together yet perceiving differently, mutually unaware of each other, is called the secret teaching. Hearing together yet perceiving differently, mutually aware of each other, is called the indeterminate teaching. The dharmas under the names of 'secret' and 'indeterminate' are simply the Tripiṭaka, shared, distinct, and perfect [teachings]. When the Buddha was in the world, meeting capacities, through a single sound they reached different understandings; broadly classified according to the methods of conversion, they temporarily receive these two names. The brief explanation of the meaning of the four teachings of the methods of conversion is finished.
