T’ien-t’ai has this to say in his Words and Phrases of the Lotus Sūtra: “Looking at heavy rainfall, one can tell the size of the dragon which causes it; looking at the abundance of lotus flowers, one can tell the depth of the pond.” Miao-lê explains it in his Annotations on the Words and Phrases of the Lotus Sūtra: “Only wise men can foretell what is going to happen; only snakes know the way of snakes.” When the sky is blue, the land is bright, so those who know the Lotus Sūtra can see the reasons for occurrences in the world.
