法華義疏 9.193

9.193

「住在空中」者，第六、住處。明佛法身住於實相虛空，如《普賢觀經》云「法身住常寂光土也」。

"Abiding in empty space" is the sixth, its place of abiding. It explains that the Buddha's dharmakāya abides in the empty space of true reality, as the Samantabhadra Contemplation Sūtra says: "The dharmakāya abides in the land of eternally quiescent light."
