I'm sure all of us agree that we need to overcome violence, but we first need to examine whether it has any value. From a strictly practical perspective, on certain occasions violence appears to be useful. We can solve a problem quickly by force. But this success is often at the expense of the rights and welfare of others. Although one problem has been solved, the seed of another has been planted.
The universe that we inhabit and our shared perception of it are the results of a common karma. Likewise, the places that we will experience in future rebirths will be the outcome of the karma that we share with the other beings living there. The actions of each of us, human or nonhuman, have contributed to the world in which we live. We all have a common responsibility for our world and are connected with everything in it.
I believe all religions pursue the same goals, that of cultivating human goodness and bringing happiness to all human beings. Though the means might appear different the ends are the same.
If the situation was such that there was only one learned lama or genuine practitioner alive, a person whose death would cause the whole of Tibet to lose all hope of keeping its Buddhist way of life, then it is conceivable that in order to protect that one person it might be justified for one or 10 enemies to be eliminated if there was no other way.
At the beginning of this century, people never questioned the effectiveness of war, never thought there could be real peace. Now, people are tired of war and see it as ineffective in solving anything.
As human beings we each have a responsibility to care for humanity. Expressing concern for others brings inner strength and deep satisfaction. As social animals, human beings need friendship, but friendship doesn't come from wealth and power, but from showing compassion and concern for others.
One interesting thing about greed is that although the underlying motive is to seek satisfaction, the irony is that even after obtaining the object of your desire you are still not satisfied. The true antidote of greed is contentment.
My own view, which does not rely solely on religious faith or even on an original idea, but rather on ordinary common sense, is that establishing binding ethical principles is possible when we take as our starting point the observation that we all desire happiness and wish to avoid suffering.
