Scientists are coming to recognise the effects of the mind on physical health. The sense of relaxation associated with inner peace involves not only being physically at ease. If you are nagged by worry or seething with anger, you’re not really relaxed. The key to relaxation is peace of mind. The relaxation gained from alcohol, drugs or just listening to music may seem attractive, but it doesn’t last.
Dalai LamaMaterial 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 LamaWe humans have existed in our present form for about a hundred thousand years. I believe that if during this time the human mind had been primarily controlled by anger and hatred, our overall population would have decreased. But today, despite all our wars, we find that the human population is greater than ever. This clearly indicates to me that love and compassion predominate in the world. And this is why unpleasant events are "news"; compassionate activities are so much a part of daily life that they are taken for granted and , therefore, largely ignored.
