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.
Nothing shocks our moral feelings so deeply as cruelty does. We can forgive every other crime, but not cruelty. The reason for this is that it is the very opposite of compassion.
We are beset by problems and if we look for their source, we find they arise because of our selfishness, because we tend to pursue our own interests at the expense of others. Our various religious traditions exist to help us reduce these problems. They all teach ways to overcome suffering through cultivating love and compassion, tolerance, patience and contentment.
I have found that the greatest degree of inner tranquility comes from the development of love and compassion. The more we care for the happiness of others, the greater is our own sense of well-being. Cultivating a close, warmhearted feeling for others automatically puts the mind at ease. It is the ultimate source of success in life.
Whatever the intellectual quality of the education given our children, it is vital that it include elements of love and compassion, for nothing guarantees that knowledge alone will be truly useful to human beings.
