2.183

若相異者，性相實有，不應道理者，量云：去來性相，應非實有，異現在故，猶如兔角，大乘真如，非定異現在，故無不定過。

Regarding "If the characteristics are different, that the nature and characteristics are substantially existent is unreasonable": The syllogism is: The natures and characteristics of the past and future should not be substantially existent, because they are different from the present, just like the horns of a hare. Mahāyāna's tathatā is not definitively different from the present, so there is no fallacy of inconclusiveness (anaikāntika).
