大乘起信論義記別記 1.43

問：各有二義，有無鉾楯，豈不相違耶？答：非直有無性不相違，亦乃相順便得成立。何者？始覺中，非從本所成之始覺，無以能顯於本覺；本覺中，非對始之本覺，無以成於始覺。是故始本四義，緣起一故，不可為異；然四義故，不可為一。猶如圓珠，隨取皆盡。護過顯德，及違成過等，各有四句，准可知之。

Question: Each having two meanings, possessing and lacking, contradiction and clash—would they not be mutually opposed? Answer: Not only are the natures of possessing and lacking not mutually opposed, they also harmonize and thus become established. How so? Within initial enlightenment, were it not the initial enlightenment accomplished from the original, there would be no way to reveal original enlightenment; within original enlightenment, were it not the original enlightenment in contrast to the initial, there would be no way to accomplish initial enlightenment. Therefore, with the four meanings of initial and original, because their pratītyasamutpāda is one, they cannot be differentiated; yet because of the four meanings, they cannot be made identical. Just like a round pearl: whichever way it is taken, it is fully embraced. Guarding against faults and revealing virtues, as well as contradiction establishing faults and so forth, each has four propositions, which should be understood accordingly.
