Quote by Gottfried Wilhelm Leibniz
To love is to find your happiness in the happiness of others.
Love is the condition in which the happiness of another person is essential to your own.
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.
