大乘起信論內義略探記 1.44

1.44

問：心體生滅者，即真心有盡，以生滅時無常住故。答：雖心體生滅而恒心體常住，以不一不異故，無二而無一性，動靜非一而無異性故，如水。依相續門即有流動、依生滅門恒不動，以不常不斷故。

Question: If the mind-essence arises and ceases, then the true mind has an end, because at the time of arising and ceasing it is not permanent. Answer: Although the mind-essence arises and ceases, the mind-essence is constantly permanent; because they are neither one nor different, having no duality and yet lacking a singular nature, movement and stillness being not one and yet lacking different natures, like water. Relying on the aspect of continuity, there is flowing motion; relying on the aspect of arising and ceasing, it is constantly unmoving, because it is neither permanent nor annihilated.
