楞伽阿跋多羅寶經註解 2.306

2.306

前四句通頌諸乘，次六句頌說一乘之意。言有心轉者，轉即起動，謂若有一念心動，雖佛乘亦非究竟，況餘乘乎？言於心行處滅，無有能乘之人，亦無所乘之法，乃至一乘法門無可建立，離名絕相，非破非立，有此等機乃為說一乘也。

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.
