More compassionate mind, more sense of concern for other's well-being, is source of happiness.
Dalai LamaWhen we speak of a calm state of mind or peace of mind, we shouldn't confuse that with an insensitive state of apathy. Having a calm or peaceful state of mind doesn't mean being spaced out or completely empty. Peace of mind or a calm state of mind is rooted in affection and compassion and is sensitive and responsive to others.
Dalai Lama
