Dalai Lama XIV, The Art of Happiness

"A disciplined mind leads to happiness, and an undisciplined mind leads to suffering."

"If you want others to be happy, practice compassion. If you want to be happy, practice compassion."

"Love and compassion are necessities, not luxuries. Without them, humanity cannot survive."

"Whether our action is wholesome or unwholesome depends on whether that action or deed arises from a disciplined or undisciplined state of mind. It is felt that a disciplined mind leads to happiness and an undisciplined mind leads to suffering, and in fact it is said that bringing about discipline within one's mind is the essence of the Buddha's teaching."
