金剛經纂要刊定記 2.219

2.219

經唯標佛者。以秦人好略故。仍存梵音者。恐濫菩提故。以菩提云覺則屬於法，今指於人故言其佛。無相濫失故不翻也。若釋其義須得唐言，故先翻對也。然覺謂覺察、覺悟，覺悟既照真本有，覺察則了妄本空。了妄本空則不逐於妄，照真本有則不迷於真。真妄既明則能破和合識、滅相續心，顯現法身，智純淨也。當爾之時，始本無二唯一覺耳。菩薩雖亦照真了妄，未得究竟，猶帶薩埵之名。唯佛如來所作究竟，故獨稱覺者。

The sūtra designates only "Buddha" because the people of Qin favored brevity. That it retains the Sanskrit sound is because of fear of confusing it with bodhi. Since bodhi is translated as "awakening," it belongs to the Dharma; here it refers to a person, hence it says "Buddha." Because there is no error of mutual confusion, it was not translated. If one explains its meaning, one must have the Chinese terms, so it is first translated and matched. Awakening means awareness and awakening: since awakening illuminates the real as originally existent, awareness discerns the deluded as originally empty. Discerning the deluded as originally empty, one does not pursue delusion; illuminating the real as originally existent, one is not confused about the real. Once the real and the deluded are clarified, one can destroy the composite consciousness and eliminate the continuous mind, manifesting the Dharma body with purely defilement-free cognition. At such a time, the initial and the original are non-dual, being only the one awakening. Although bodhisattvas also illuminate the real and discern the deluded, they have not attained the ultimate and still carry the name sattva. Only the Buddha, the Tathāgata, has accomplished all that was to be done to the ultimate; hence he alone is called the Awakened One.
