If you have fear of some pain or suffering, you should examine whether there is anything you can do about it. If you can, there is no need to worry about it; if you cannot do anything, then there is also no need to worry.
Dalai LamaThe lessons we have begun to learn make me hopeful, that human beings will become friendlier, more harmonious, less harmful. Compassion and the seeds of peace will be able to flourish. At the same time, every individual is responsible to help guide our global family in the right direction. Good wishes alone are not enough; we have to take responsibility. Large human movements spring from individual human initiatives
