法華玄論 1.111

1.111

Answer: The 'revealed teaching' is the expedient teaching. It explains that the people of the three vehicles each practice their own causes and all attain the fruition [appropriate to them]; this matter is easy to understand. Just as three external seeds each sprout into three [distinct] shoots whose characteristics are easy to understand, it is therefore called 'revealed'. The 'secret teaching' refers to the extremely profound teaching, which explains that there are no three vehicles, but only the one vehicle; hence it is called 'secret'.
