Because we all share an identical need for love, it is possible to feel that anybody we meet, in whatever circumstances, is a brother or sister. No matter how new the face or how different the dress and behavior, there is no significant division between us and other people.

We all have the potential to show others love and affection, but as we progress in our materialistic world, these values tend to remain dormant. We can develop them on the basis of common sense, common experience and scientific findings. The response to the recent tragedy in the Philippines is an example of how such values are awakened; people helped simply because others are suffering and in need of support.

So the first step in seeking happiness is learning. We first have to learn how negative emotions and behaviors are harmful to us and how positive emotions are helpful.
