法華玄論 9.44

9.44

答：上已說之，今當更解。尋本迹義者，必本妙而迹麁，而今乃以釋迦之麁為本、淨土之妙為迹者，則知釋迦非復本矣。釋迦既非復本，則丈六非真身也。又一事之中得雙顯二義。以釋迦指淨土為化迹則淨土佛非實身，釋迦之麁必非妙身則知釋迦亦為迹矣。是以二身皆悉是迹，然後始知法身妙極為化之本也。

Answer: This was already explained above, but shall now be explained further. In investigating the meaning of root and trace, the root is necessarily subtle and the trace crude; yet now, taking Śākyamuni's crudeness as the root and the pure land's subtlety as the trace, one knows that Śākyamuni is no longer the root. Since Śākyamuni is no longer the root, the sixteen-foot form is not the true body. Moreover, within a single event, two meanings are jointly revealed: when Śākyamuni points to the pure land as a transformed trace, the buddha of the pure land is not the real body; and since Śākyamuni's crudeness cannot be the subtle body, one knows that Śākyamuni is also a trace. Therefore, both bodies are entirely traces, and only then does one begin to know that the utmost subtlety of the dharmakāya is the root of transformations.
