法華義疏 10.38

10.38

由遠離諸緣方得攝心耳，所以在後明之。又遠離十緣謂菩薩戒，常好坐禪謂菩薩定，後明觀空即智慧也。

Only by staying far away from various conditions can one collect the mind; therefore it is explained later. Furthermore, keeping far away from the ten conditions refers to the bodhisattva's precepts; always delighting in sitting in dhyāna refers to the bodhisattva's concentration; and the subsequent explanation of contemplating emptiness is wisdom.
