First, the dharmakāya is not two, while trace bodies are not one, yet it was not known whether the non-dual body is subject to birth and cessation or free from birth and cessation. Next, it was illuminated that the dharmakāya is free from birth and cessation, while the response body has birth and cessation; though it was known that the dharma[kāya] and the response [body] differ regarding birth and cessation, it was not known whether Śākyamuni newly realized it or had realized the dharmakāya long ago. Next, its duration and recency were illuminated. All buddhas possess the former two; Śākyamuni possesses all three.
