首楞嚴義疏注經 4.449

4.449

三變之義古今多解，各見其文不能具敘。今所解者，不加別法以變其數，只將今文過、現、未來進動算位，便成一千二百功德。如第一位，三世、四方宛轉十二，便成一疊，算位即是一橫二竪已成過去。第二即變過去一世以為現在，進動算位，一竪二橫，成百二十，為第二疊。第三又即變現在世以為未來，進動算位，一橫二竪成一千二百，為第三疊。能變之法既唯三世，所變之數亦止千二，故無增減。

The meaning of the three transformations has had many explanations past and present, each seeing its own text, which cannot be fully narrated. What is explained now does not add any other method to transform the count, but simply takes the advance and movement of calculating positions through past, present, and future in the present text, and it immediately forms one thousand two hundred virtues. For instance, in the first position, the three times and four directions revolve to make twelve, which immediately forms one layer; the calculating position is one horizontal and two verticals, already becoming the past. Second, one then transforms the single past era into the present, advancing the calculating position to one vertical and two horizontals, making one hundred twenty, which is the second layer. Third, one then again transforms the present era into the future, advancing the calculating position to one horizontal and two verticals, making one thousand two hundred, which is the third layer. Since the method capable of transforming is only the three times, the count transformed also stops at twelve hundred; hence there is neither increase nor decrease.
