3.25

In explaining "spiritual power", it is first explained in terms of phenomena, which is Śākyamuni's power of supernatural penetration. However, when the Great Sage acts, phenomena must symbolize principle, and both meanings must be present; therefore, both phenomenal and principle interpretations say "or alternatively". In "the Tathāgata is simply true suchness" and so forth: it explains Tathā (ru) as true suchness, and Āgata (lai) as spiritual power, so as to clarify the Tathāgata's spiritual power. In "this true suchness has spiritual power": "spiritual" is defined as fathomless, and "power" is defined as capable function. Being fathomless, the natural principle is profound; having capable function, the power of transformation is vast. In "riding this spiritual power and coming", it means riding true suchness to have a responsive body, hence it is said "and coming"—that is, riding the path of true reality to come and realize correct enlightenment.
