妙法蓮華經玄義 7.243

7.243

譬如泥蓮四微，處空蓮四微，初後不異，此名蓮子本末等。一切眾生亦如是，本有四德，隱名如來藏，修成四德顯，名為法身，性德修德，常樂我淨，一而無二，是名佛界十如本末究竟等。經言：「眾生如佛如，一如無二如。」即其義也。

For instance, the four subtle elements of the lotus in the mud and the four subtle elements of the lotus in open space do not differ between beginning and end; this is called the lotus seed's equality of beginning and end. All sentient beings are also like this: originally possessing the four virtues, when concealed it is called the tathāgata-garbha; through cultivation, the four virtues become manifest, and it is called the dharma-kāya. The inherent virtue and the cultivated virtue, permanent, blissful, self, and pure, are one and not two; this is called the ultimate equality of beginning and end of the ten suchnesses of the buddha realm. A sūtra says, 'The suchness of sentient beings and the suchness of buddhas are one suchness without distinction'—this is its meaning.
