We should reflect on the idea that since the beginning of time sentient beings have been mentally unstable because they have been slaves of delusion, they lack the eye of wisdom to see the path leading to nirvana and enlightenment, and they lack the necessary guidance of a spiritual teacher. Moment by moment they are indulging in negative actions, which will eventually bring about their downfall.
From a Buddhist point of view, the actual experience of death is very important. Although how or where we will be reborn is generally dependent on karmic forces, our state of mind at the time of death can influence the quality of our next rebirth. So at the moment of death, in spite of the great variety of karmas we have accumulated, if we make a special effort to generate a virtuous state of mind, we may strengthen and activate a virtuous karma, and so bring about a happy rebirth.
I hope that at this moment you are thinking of yourself as a human being rather than as an American, Asian, European, African, or member of any particular country. These loyalties are secondary.
Life does not wait: Whether we spend our lives meaningfully or not, the time will be used up moment by moment.
Basically, a human being is a social animal. So, if you create some short moment of happiness for people, you get deep satisfaction.
