注大乘入楞伽經 8.102

8.102

此明若愛取諸根滅，不相續生自惡覺觀分別苦樂受者，修如是行，或得滅定四禪，入四諦解脫，便妄生得真解脫想。故《法華》云「但盡生死」，名為解脫，其實未得一切解脫也。自此已上，明如來藏與出世間聲聞、緣覺劣無漏善法為因。

This explains that if the sense faculties of craving and grasping cease, not continuing to produce their own evil coarse and subtle thoughts distinguishing painful and pleasant feelings, those who practice such a path may attain the cessation absorption or the four dhyānas, entering the liberation of the four noble truths, and then falsely produce the notion of having attained true liberation. Therefore the Lotus Sūtra says that "merely exhausting saṃsāra" is called liberation, but in truth they have not yet attained universal liberation. From here upward, it explains the tathāgatagarbha as the cause of the inferior uncontaminated wholesome dharmas of the supramundane śrāvakas and pratyekabuddhas.
