What is wisdom?

Wisdom, in the Lotus Sutra, does not simply mean being smart, it is far more profound. Essentially, it is to have an excellent "heart". Wisdom signifies humanity and force of character borne of strength, breath and profundity of spirit. Nichiren says, " The wise may be called human. " He also explains that one who preserves in the correct way of life, unswayed by praise and censure, is truly wise.
