T’ien-t’ai explains, “The profound doctrine of all phenomena as ultimate reality is the Lotus Sūtra that exists originally and always.” This annotation means that “the deep doctrine of ultimate reality” expounded in the theoretical section of the Lotus Sūtra is called in the essential section the Sūtra of the Lotus Flower of the Wonderful Dharma which exist originally and always. This interpretation is not easy to understand, so please spare no effort in contemplating this.
