The reason why love and compassion bring the greatest happiness is simply that our nature cherishes them above all else. The need for love lies at the very foundation of human existence. It results from the profound interdependence we all share with one another. We are all connected as One.
However capable and skillful an individual may be, left alone, he or she will not survive. However vigorous and independent one may feel during the most prosperous periods of life, when one is sick or very young or very old, one must depend on the support of others.
Inter-dependence, of course, is a fundamental law of nature. Not only higher forms of life but also many of the smallest insects are social beings who, without any religion, law or education, survive by mutual cooperation based on an innate recognition of their interconnectedness. The most subtle level of material phenomena is also governed by interdependence. All phenomena from the planet we inhabit to the oceans, clouds, forests and flowers that surround us, arise in dependence upon subtle patterns of energy. Without their proper interaction, they dissolve and decay.
It is because our own human existence is so dependent on the help of others that our need for love lies at the very foundation of our existence. Therefore we need a genuine sense of responsibility and a sincere concern for the welfare of others.
If you have a sincere and open heart, you naturally feel self- worth and confidence, and there is no need to be fearful of others.
