Why we don’t understand as much as we think we do

"O People of Persia! Open your eyes! Pay heed! Release yourselves from this blind following of the bigots, this senseless imitation which is the principal reason why men fall away into paths of ignorance and degradation. See the true state of things. Rise up; seize hold of such means as will bring you life and happiness and greatness and glory among all the nations of the world." (Abdu'l-Baha, The Secret of Divine Civilization, p. 104)
