On the Treasure Tower, WND, p. 299
In essence, the appearance of the treasure tower indicates that on hearing the Lotus Sutra the three groups of voice-hearers perceived for the first time the treasure tower within their own lives. Now Nichiren’s disciples and lay supporters are also doing this. In the Latter Day of the Law, no treasure tower exists other than the figures of the men and women who embrace the Lotus Sutra. It follows, therefore, that whether eminent or humble, high or low, those who chant Nam-myoho-renge-kyo.are themselves the treasure tower, and, likewise, are themselves the Thus Come One Many Treasures. No treasure tower exists other than Myoho-renge-kyo. The daimoku of the Lotus Sutra is the treasure tower, and the treasure tower is Nam-myoho-renge-kyo.
