Taho corresponds to number 9 on the Gohonzon Diagram.
Namu Taho Nyorai means "Devotion to Many Treasures Thus Come One."
When we repeat (as Taho does) the 16th chapter of the Lotus Sutra, we reveal the treasures of our life. These treasures are both visible and invisible. . . Like the moon, which is both seen and unseen. Like jade in a house.
The Treasure Tower is our life itself.
"In essence, the appearance of the Treasure Tower indicates that the three groups of Shakyamuni's disciples attained enlightenment only when they heard the Lotus Sutra and perceived the Treasure Tower within their own lives. Now Nichiren's disciples are doing the same. In the Latter Day of the Law, there is no Treasure Tower other than the figures of the men and women who embrace the Lotus Sutra. It follows, therefore, that those who chant Nam-myoho-renge-kyo, irrespective of social status, are themselves the Treasure Tower and likewise they themselves are Taho Buddha."The seven jewels on the Treasure Tower are the senses that perceive the objective world. For this reason Taho represents objective reality and Shakyamuni represents subjective wisdom."Therefore, Abutsu-bo is the Treasure Tower itself, and the Treasure Tower is Abutsu-bo himself. No other knowledge is purposeful." (ibid.)
"The true aspect of all phenomena indicates the two Buddhas Shakyamuni and Taho [seated together in the Treasure Tower]. Taho represents all phenomena and Shakyamuni, the true aspect. The two Buddhas also indicate the two principles of the truth as object and the wisdom to grasp it. Taho signifies the truth , as object and Shakyamuni, the wisdom. Although these are two, they are fused into one in the Buddha's enlightenment."
