Peace of mind is the basis of a healthy body and a healthy mind; so peace of mind, a calm mind, is very, very important.
Dalai LamaOur most valuable teachers are our enemies.While our friends can help us in many ways, only our enemies can provide us with the challenge we need to develop tolerance, patience, and compassionthree virtues essential for building character, developing peace of mind, and bringing us true happiness.
Dalai LamaNowadays the world is becoming increasingly materialistic, and mankind is reaching toward the very zenith of external progress, driven by an insatiable desire for power and vast possessions. Yet by this vain striving for perfection in a world where everything is relative,they wander even further away from inward peace and happiness of the mind.
