金剛般若經贊述 2.307

2.307

“If he comes” refers to coming when achieving enlightenment; “if he goes” refers to going upon entering cessation; “if he sits” refers to the time of preaching the Dharma and benefiting others; “if he lies down” refers to announcing the mark of cessation. The manifestation body has these, whereas the dharmakāya lacks them; hence it says “he comes from nowhere and goes nowhere.” It is like the moon in the sky casting its reflection upon the water: when the water is clear, it appears; when the water is turbid, it is hidden. The body of the moon originally has no coming or going; it is due to the water that arising and perishing appear. The dharmakāya is fundamentally serene and quiescent; it is due to the mind that coming and going are seen. A master says: The dharmakāya fundamentally has no coming; it is because sentient beings face toward the Buddha that they see him come—this is “coming without coming,” just like hurrying to an elevated terrace to look out into the distance, gazing at one's reflected countenance and bowing oneself down. The dharmakāya fundamentally has no extinction; it is because sentient beings grow weary of the Buddha that in the midst of non-going they see him go, just like sailing on a swift boat traveling east, looking at a calm pond and seeing it flow west—this is “going without going.”
