妙法蓮華經玄義 7.123

7.123

○第六、約三世料簡者，文云：「如來自在神通之力，如來大勢威猛之力，如來師子奮迅之力。」即是三世益物之文。若過去最初所證權實之法，名為本也，從本證已，後方便化他。開三顯一、發迹顯本者，還指最初為本；中間示現、發迹顯本，亦指最初為本；今日發迹顯本，亦指最初為本；未來發本顯迹，亦指最初為本。三世乃殊，毘盧遮那一本不異，如百千枝葉，同趣一根（云云）。

Section 6: Examining in terms of the three periods of time. The text states: 'The Tathāgata's power of sovereign supernatural penetration, the Tathāgata's power of great formidable might, the Tathāgata's power of the lion's sprint.' These are texts concerning the benefiting of beings across the three periods of time. If the provisional and real dharmas first realized in the past are called the 'original source', then after the original realization, one subsequently employs expedient means to convert others. When one opens the three and reveals the one, or discloses the traces and reveals the original source, this points back to the very first as the original source; intermediate manifestations that disclose traces and reveal the original source also point to the very first as the original source; today's disclosing of traces and revealing of the original source also points to the very first as the original source; and future disclosures of the original source and revelations of traces will also point to the very first as the original source. Though the three periods of time differ, Vairocana is one original source without distinction, just as a hundred thousand branches and leaves all lead back to a single root (and so forth).
