“A soul that makes virtue its companion is like an over-flowing well, for it is clean and pellucid, sweet and wholesome, open to all, rich, blameless and indestructible.”

“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious?
