楞伽阿跋多羅寶經註解 2.306

2.306

The first four lines generally praise the various vehicles; the following six lines praise the intention of speaking of the One Vehicle. "Mind continues to revolve" means that revolving is movement: it means that if there is even a single thought of mental movement, then even the Buddha Vehicle is not ultimate, let alone the other vehicles. It means that when the realm of mental activity is extinguished, there is no person who can ride, nor is there any dharma that is ridden, and even the Dharma-gate of the One Vehicle cannot be established; it is free from designations and cut off from marks, neither refuting nor establishing; it is for faculties such as these that the One Vehicle is taught.
