法華論疏 1.15

1.15

言正覺海者，一法身佛，遍一切處，如海之大。故《普賢觀》云「毘盧舍那一切處」也。二深如海，謂七辨不能說、五眼忘其照，故謂深也。三一味如海，平等法身一身如味。四法身具一切功德，如海之備眾珍。餘法僧易知。

Regarding the words "ocean of perfect awakening": First, the dharmakāya Buddha pervades all places, as vast as an ocean; therefore the Samantabhadra Meditation Sūtra states, "Vairocana is in all places." Second, it is as deep as an ocean, meaning that the seven eloquence-faculties cannot explain it and the five eyes lose their illumination; therefore it is called deep. Third, it is of single taste like the ocean: the equal dharmakāya is one body like a single taste. Fourth, the dharmakāya possesses all merits, just as the ocean is provided with all treasures. The remaining Dharma and Saṃgha are easy to understand.
