According to Buddhism, to love is an action. It's that force that motivates people to become better, to improve themselves in order to reach eternity and happiness. Love brings out the best in people, as when they love, the target is not themselves but the beloved ones. This wish to serve others is said to be a reflection of an innate knowledge that everybody is connected through the same principle, and therefore, it is an illusion to believe that one can achieve true happiness while those around haven't attained it . So, love is the action that makes people step out of their own ego and work in favour of the whole in a search for fulfillment.
When a person truly loves another, nothing can be expected in return, because the motivation is the spiritual growth of the beloved ones, not reciprocity. If a person loves another only if the other person loves him or her too, or only if the other person is faithful, then, this conditional love hides an unconscious assumption that it is necessary to be loved in order to love, and, according to Buddhist philosophy, this is a mistake as love ought to be an end in itself.
True love is free from emotional attachment. The greatest lesson of Buddhism is that detachment does not mean that loving is meaningless. Rather, detachment is the state of mind that allows people to love even more, abundantly, and for the right reasons – because every single living being is a small part of the same universal body and not loving the neighbour would be the same as not loving oneself.
http://www.dalailama.com/messages/compassionEven when we engage in ordinary conversation in everyday life, if someone speaks with human feeling we enjoy listening, and respond accordingly; the whole conversation becomes interesting, however unimportant the topic may be. On the other hand, if a person speaks coldly or harshly, we feel uneasy and wish for a quick end to the interaction. From the least to the most important event, the affection and respect of others are vital for our happiness.
The more we care for the happiness of others, the greater our own sense of well-being becomes. Cultivating a close, warm-hearted feeling for others automatically puts the mind at ease. This helps remove whatever fears or insecurities we may have and gives us the strength to cope with any obstacles we encounter. It is the ultimate source of success in life.
As long as we live in this world we are bound to encounter problems. If, at such times, we lose hope and become discouraged, we diminish our ability to face difficulties. If, on the other hand, we remember that it is not just ourselves but every one who has to undergo suffering, this more realistic perspective will increase our determination and capacity to overcome troubles. Indeed, with this attitude, each new obstacle can be seen as yet another valuable opportunity to improve our mind!
Thus, we can strive gradually to become more compassionate, that is we can develop both genuine sympathy for others' suffering and the will to help remove their pain. As a result, our own serenity and inner strength will increase.
Our need for loveUltimately, 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. However capable and skilful 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.
We have to consider what we human beings really are. We are not like machine-made objects. If we are merely mechanical entities, then machines themselves could alleviate all of our sufferings and fulfil our needs.
