妙法蓮華經玄義 2.9

2.9

眾生法為二：先列法數，次解法相。數者，經論或明一法攝一切法，謂心是：三界無別法，唯是一心作。或明二法攝一切法，所謂名、色：一切世間中，但有名與色。或明三法攝一切法：謂命、識、煖。如是等增數，乃至百千。今經用十法攝一切法：「所謂諸法：如是相、如是性、如是體、如是力、如是作、如是因、如是緣、如是果、如是報、如是本末究竟等。」南岳師讀此文皆云如，故呼為十如也。

The dharmas of sentient beings are divided into two: first, listing the numerical dharmas, and next, explaining the characteristics of the dharmas. As for the numbers, sūtras and treatises sometimes clarify that a single dharma subsumes all dharmas, which is the mind: 'In the three realms there is no other dharma; it is created by the one mind alone.' Sometimes they clarify that two dharmas subsume all dharmas, namely name and form: 'In all the world, there are only name and form.' Sometimes they clarify that three dharmas subsume all dharmas, namely life, consciousness, and warmth. Such increments in number go up to hundreds of thousands. The present sūtra uses ten dharmas to subsume all dharmas: 'That is to say, of all dharmas: such appearance, such nature, such substance, such power, such activity, such cause, such condition, such effect, such retribution, and such ultimate equality of beginning and end.' The master of Nanyue read this text taking all as suchness (ru), and therefore called them the ten suchnesses.
