So long as space remains, So long sentient beings' suffering remain, I will remain, In order to help, in order to serve... I am nothing but a servant to provide to others. So if you provide some happiness, some comfort to others, then your life becomes meaningful. If your life creates problems or suffering to others, then there's no meaning to your existence.
Dalai LamaAll living beings have experience of pleasure and pain, and we are among them. What makes human beings different is that we have a powerful intelligence and a much greater ability to achieve happiness and avoid suffering. Real happiness and friendship come not from money or even knowledge, but from warm-heartednes s. Once we recognize this we will be more inclined to cultivate it.
Dalai Lama
