The Shingon monk Dohan regarded the two great Buddhas, Amitābha and Vairocana, as one and the same Dharmakāya Buddha and as the true nature at the core of all beings and phenomena. There are several realizations that can accrue to the Shingon practitioner of which Dohan speaks in this connection, as James Sanford points out:

With regard to śūnyatā, the massive size and brilliance of Vairocana statues serve as a reminder that all conditioned existence is empty and without a permanent identity, whereas the Dharmakāya is beyond concepts.
