六、類通三種大乘者：一，性乘；二，得乘；三，隨乘。一、性乘者，《涅槃經》云：「一切眾生，即大乘也。」二、得乘者，即智慧能得理乘，故名得乘。三、隨乘者，即是大方便隨順智慧，故名隨乘。真性解脫，即是理乘；實慧解脫，即是得乘；方便解脫，即是隨乘也。

Sixth, analogously correlating the three kinds of Great Vehicle: first, the vehicle of the nature; second, the vehicle of attainment; third, the vehicle of accordance. First, as for the vehicle of the nature, the Nirvāṇa Sūtra states: 'All sentient beings are themselves the Great Vehicle.' Second, the vehicle of attainment is wisdom able to attain the vehicle of principle; hence it is named the vehicle of attainment. Third, the vehicle of accordance is great expedient means according with wisdom; hence it is named the vehicle of accordance. The liberation of the true nature is the vehicle of principle; the liberation of real wisdom is the vehicle of attainment; the liberation of expedient means is the vehicle of accordance.
