The wise men of antiquity, when they wished to make the whole world peaceful and happy, first put their own States into proper order. Before putting their States into proper order, they regulated their own families. Before regulating their families, they regulated themselves. Before regulating themselves, they tried to be sincere in their thoughts. Before being sincere in their thoughts, they tried to see things exactly as they really were.
I saw some piglets suckling their dead mother. After a short while they shuddered and went away. They had sensed that she could no longer see them and that she wasn't like them any more. What they loved in their mother wasn't her body, but whatever it was that made her body live.
Behave when away from home as though you were in the presence of an honored guest. Employ the people as though you were assisting at an important sacrifice. Do not do to others what you would not like yourself. Then there will be no feelings of opposition to you, whether it is the affairs of a state that you are handling or the affairs of a family.

Love others as you would love yourself, judge others as you would judge yourself, cherish others as you would cherish yourself. When you wish for others as you wish for yourself and when you protect others as you would protect yourself, that's when you can say it's true love.
