Regarding "by contrast with" and what follows: the text below states: "One should know that defiled dharmas and pure dharmas are entirely relative to each other." Here, it is temporarily established as inherently existing by contrast with newly arisen [enlightenment]. Because actualized enlightenment newly arises through cultivation, whereas original enlightenment is inherently and primordially present by its nature, the "original" is established by contrast with the "actualized". Regarding "furthermore" and what follows: explaining according to a distinct meaning. The preceding part explained the name "original" by contrast with the "actualized"; this part explains the name "original" because it generates the "actualized". Tracing its source, actualized enlightenment is generated by the original: with internal vāsanā as cause and external conditions as supportive power, it bursts forth into existence and is therefore named "actualized"; because it generates the actualized, it is named "original". If there were nothing generated, it would not be called "original", just as a woman can receive the title of "mother" only after giving birth to a child.
