Nichiren Shonin explained in the Daimoku of the Lotus Sutra (1266), Kaimoku Sho (1272) and Kanjin Honzon Sho (1273) that the single character of Myo is extremely powerful. Myo, in fact, possesses the three meanings of:

1. to open, reveal
2. to be endowed and perfect,
3. to bring back to life, revive, resurrect, have the capacity to transform poison into medicine (and negative into positive).
