There is no self-interest completely unrelated to others' interests. Due to the fundamental interconnectedness which lies at the heart of reality, your interest is also my interest. From this it becomes clear that "my" interest and "your" interest are intimately connected. In a deep sense, they converge.
Dalai LamaRight from the moment of our birth, we are under the care and kindness of our parents, and then later on in our life when we are oppressed by sickness and become old, we are again dependent on the kindness of others. Since at the beginning and end of our lives we are so dependent on other's kindness, how can it be in the middle that we would neglect kindness towards others?
Dalai LamaAccording to Buddhist psychology most of our troubles stem from attachment to things that we mistakenly see as permanent.
Dalai LamaAnger cannot be overcome by anger. If someone is angry with you, and you show anger in return, the result is a disaster. On the other hand, if you control your anger and show its opposite - love, compassion, tolerance and patience - not only will you remain peaceful, but the other person's anger will also diminish.
Dalai LamaOnce we have a firm practice of compassion our state of mind becomes stronger which leads to inner peace, giving rise to self-confidence, which reduces fear. This makes for constructive members of the community. Self-centredness on the other hand leads to distance, suspicion, mistrust and loneliness, with unhappiness as the result.
