All 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.
