維摩經玄疏 2.143

2.143

此即是三藏教折法觀、通教體法觀十法成乘，意在此也。但別教三觀十法成乘，明六種乘，義意不同，分別事繁。

This is precisely the meaning of the contemplation of breaking dharmas in the Tripiṭaka teaching and the contemplation of embodying dharmas in the shared teaching forming the vehicles through the ten dharmas. However, regarding the distinctive teaching's three contemplations and ten dharmas forming the vehicle, the meaning and significance in explaining the six kinds of vehicles are different, and distinguishing them involves complex details.
