妙法蓮華經玄義 6.126

6.126

一、就理妙者，一切諸法無非中道，無離文字而說解脫。文字性離即是解脫，一切所說即理而妙。譬如龍雨雨，而處處不同，或水、或火、或刀杖，理亦如是，理具情乖順耳，乖故為麁，理順為妙。

First, regarding subtlety in terms of principle: among all dharmas, there is none that is not the Middle Way, and liberation is not expounded apart from written words. The nature of written words being transcendent is itself liberation; everything that is expounded is subtle by being identical with principle. For example, when a dragon sends down rain, it differs from place to place, sometimes being water, sometimes fire, or sometimes swords and staves. Principle is also like this: principle is complete, but sentiments may be contrary or conformable to it; because contrary, it is crude, and by conforming to principle, it is subtle.
