瑜伽論記 2.175

2.175

結牒彼言：性若是無，不可顯了等者，有相法中，若無彼性，不可顯了，如角中乳、水中酪等，若有彼性，方可顯了，如乳中酪、鑛中金，不遮有無性，但遮果住因。

Concluding by restating their assertion: "If the nature is non-existent, it cannot be manifested, etc.": Among dharmas possessing characteristics, if that nature does not exist, it cannot be manifested, like milk in horns or curds in water; if that nature exists, only then can it be manifested, like curds in milk or gold in ore. This does not refute the existence or non-existence of natures, but merely refutes that the effect abides within the cause.
