三、合。疏　水隨風動者，即前大海因風波動也。以水下，喻，文可知。所況者，應云以心不能自生，要因無明以成識等。無明不能自現妄相，要因心方現妄相，故無明動相即心動相，無別體也。故前云：染法望真，是真之相；若望無明，是無明相也。

Third, the application. Commentary: 'Water moves according to wind' refers to the great ocean moving in waves due to the wind mentioned earlier. Regarding 'because water...' below: the metaphor's text can be understood. As for what is illustrated, one should say that because the mind cannot arise by itself, it must rely on ignorance to form consciousness and so forth. Ignorance cannot manifest false marks by itself; it must rely on the mind to manifest false marks. Therefore, the mark of motion in ignorance is precisely the mark of motion in the mind, having no distinct essence. Hence it was said earlier: 'When defiled dharmas are viewed in relation to the true, they are marks of the true; when viewed in relation to ignorance, they are marks of ignorance.'
