The rationale for loving others is the recognition of the simple fact that every living being has the same right to and the same desire for happiness, and not suffering, and the consideration that you as one individual are one life unit as compared with the mulititude of others in their ceaseless quest for happiness.
In dealing with those who are undergoing great suffering, if you feel "burnout" setting in, if you feel demoralized and exhausted, it is best, for the sake of everyone, to withdraw and restore yourself. The point is to have a long-term perspective.
A wider of more altruistic attitude is very relevant in today's world. If we look at the situation from various angles, such as the complexity and inter-connectedness of the nature of modern existence, then we will gradually notice a change in our outlook, so that when we say 'others' and when we think of others, we will no longer dismiss them as something that is irrelevant to us. We will no longer feel indifferent.
Our visit to this planet is short, so we should use our time meaningfully, which we can do by helping others wherever possible. And if we cannot help others, at least we should try not to create pain and suffering for them.
Cultivating care and concern for others gives rise to a kind of inner strength. No matter what difficulties or problems you face, in this wider context they’ll seem less significant and troubling to you. The inner strength, self-confidence and courage you gain by focussing on others’ needs instead of your own, brings with it a deep, calm sense of satisfaction.
We need to strengthen such inner values as contentment, patience and tolerance, as well as compassion for others. Keeping in mind that it is expressions of affection rather than money and power that attract real friends, compassion is the key to ensuring our own well-being.
If you have peace of mind, when you meet with problems and difficulties they won’t disturb your inner peace. You’ll be able to employ your human intelligence more effectively. But, if your mental state is disturbed, full of emotion, it is very difficult to cope with problems, because the mind that is full of emotion is biased, unable to see reality. So whatever you do will be unrealistic and naturally fail.
A compassionate attitude opens our inner door, and as a result it is much easier to communicate with others. If there is too much self-centered attitude, then fear, doubt and suspicion come and as a result our inner door closes. Then it is very difficult to communicate with others.
