Material objects give rise to physical happiness, while spiritual development gives rise to mental happiness. Since we experience both physical and mental happiness, we need both material and spiritual development. This is why, for our own good and that of society we need to balance material progress with inner development.
Dalai LamaAs human, we all have the same human potential, unless there is some sort of retarded brain function. The wonderful human brain is the source of our strength and the source of our future, provided we utilize it in the right direction. If we use the brilliant human mind in the wrong way, it is really a disaster.
Dalai LamaOnce your mind is calm and full of love, there is no room for hatred or fear. Others will trust you because of your open heart.
Dalai LamaThe ultimate source of my mental happiness is my peace of mind. Nothing can destroy this except my own anger.
Dalai LamaWhat is the relationship between spirituality and ethical practice? Since love and compassion and similar qualities all, by definition, presume some level of concern for others' well-being, they presume ethical restraint. We cannot be loving and compassionate unless at the same time we curb our own harmful impulses and desires.
