““As there is no evil however small but may cause him to groan under it, who has his heart undisciplined, so there is no calamity however great but may cause him to despair, who has his feelings in control. A laughing child would cry, a crying child would laugh, without a sufficient cause. 'It can be teased or tickled into anything.' A grown-up child is he who cannot hold sway over his passions. He should die a slave to his heart, which is wayward and blind, if he be indulgent to it.””
