In experience the practice of love brings peace of mind to myself and helps others. Foolish selfish people are always thinking of themselves, and the result is always negative. Wise persons think of others, helping them as much as they can, and the result is happiness. Love and compassion are beneficial both for you and for others. Through your kindness toward others, your mind and heart will open to peace.
— His Holiness The Dalai Lama, How to Expand Love
