To become cold with the coldness of the world is weakness, and to become broken by the hardness of the world is feebleness, but to live in the world and yet to keep above the world is like walking on the water. There are two essential duties for the man of wisdom and love; that is to keep the love in our nature ever increasing and expanding and to strengthen the will so that the heart may not be easily broken. Balance is ideal in life; man must be fine and yet strong, man must be loving and yet powerful.
