Regarding "Initially for the two vehicles, explaining solely the four truths, only stating that other-dependent and consummate [natures] exist," etc.: The dharmas of the four truths are simply other-dependent and consummate. The two truths of suffering and origination, being defiled causes and results, are only the other-dependent nature. The two truths of cessation and path, being pure causes and results, are the consummate [nature]. Although the untainted path truth arises from conditions, here it is subsumed under non-perverted consummation; hence both of the latter two truths are subsumed under the consummate. Because the dharmas of the four truths are real causes and results, and do not subsume the substanceless dharmas of the imagined [nature], it says "only stating that other-dependent and consummate [natures] exist," etc.
