四明十義書 2.50

2.50

且事法觀，縱不於陰揀境，約行觀為何不於陰揀境耶？若事法觀縱不可修證，約行觀為何不可修證耶？

Now, even if phenomenal contemplation does not select its object from the aggregates, why should contemplation according to practice not select its object from the aggregates? Even if phenomenal contemplation cannot be cultivated and realized, why should contemplation according to practice be incapable of cultivation and realization?
