We can never obtain peace in the world if we neglect the inner world and don't make peace with ourselves. World peace must develop out of inner peace. Without inner peace it is impossible to achieve world peace, external peace. Weapons themselves do not act. They have not come out of the blue. Man has made them. But even given those weapons, those terrible weapons, they cannot act by themselves. As long as they are left alone in storage they cannot do any harm. A human being must use them. Someone must push the button. Satan, the evil powers, cannot push that button. Human beings must do it.
In order to be happy we must first possess inner contentment; and inner contentment doesn't come from having all we want; but rather from wanting and appreciating being grateful for all we have.
In the interests of everyone the artist had a responsibility to use his medium well. In the Tibetan culture, most of the paintings are of deities or Buddhas, and they try to send a message of the value of the spiritual.
We should practice by showing one another love and helping one another. It is a mistake to pursue happiness and to seek to the avoid suffering by deceiving and humiliating other people. We must try to achieve happiness and eliminate suffering by being good-hearted and well-behaved.
The problem isn't materialism as such. Rather it is the underlying assumption that full satisfaction can arise from gratifying the senses alone. Unlike animals whose quest for happiness is restricted to survival and to the immediate gratification of sensory desires, we human beings have the capacity to experience happiness at a deeper level which, when achieved, can overwhelm unhappy experiences.
According to Buddhism, individuals are masters of their own destiny. And all living beings are believed to possess the nature of the Primordial Buddha Samantabhadra, the potential or seed of enlightenment, within them. So our future is in our own hands. What greater free will do we need?
Whether you believe in God or not does not matter so much, whether you believe in Buddha or not does not matter so much; as a Buddhist, whether you believe in reincarnation or not does not matter so much. You must lead a good life. And a good life does not mean just good food, good clothes, good shelter. These are not sufficient. A good motivation is what is needed: compassion, without dogmatism, without complicated philosophy; just understanding that others are human brothers and sisters and respecting their rights and human dignity.
