Men enslaved by self, passionate, proud, and condemnatory, believe their particular creed or religion to be the Truth, and all other religions to be error; and they proselytize with passionate ardor. There is but one religion, the religion of Truth. There is but one error, the error of self. Truth is not a formal belief; it is an unselfish, holy, and aspiring heart, and he who has Truth is at peace with all, and cherishes all with thoughts of love.
— James Allen
