The great benefit of science is that it can contribute tremendously to the alleviation of suffering at the physical level, but it is only through the cultivation of the qualities of the human heart and the transformation of our attitudes that we can begin to address and overcome our mental suffering...
Compassion suits our physical condition, whereas anger, fear and distrust are harmful to our well-being. Therefore, just as we learn the importance of physical hygiene to physical health, to ensure healthy minds, we need to learn some kind of emotional hygiene.
In this century we have made remarkable material progress, but basically we are the same as we were thousands of years ago. Our spiritual needs are still very great.
Yet even the rich have their own kind of suffering, anxiety, doubt, and fear. So in many cases, wealthy people aren't happy! And once those with material wealth encounter small difficulties, their amount of mental suffering is sometimes bigger than it is for those who have faced such difficulties every day.
The proper way to create friends is to have a warm heart, not simply money or power. The friend of power and the friend of money are something different.
The creation of a more peaceful and happier society has to begin from the level of the individual, and from there it can expand to one's family, to one's neighborhood, to one's community and so on.
When we are motivated by compassion and wisdom, the results of our actions benefit everyone, not just our individual selves or some immediate convenience. When we are able to recognize and forgive ignorant actions of the past, we gain strength to constructively solve the problems of the present.
The more adept we become at cultivating an altruistic attitude, the happier we will feel and the more comfortable will be the atmosphere around us. But if our emotions fluctuate wildly and we easily give in to hatred and jealousy, even our friends will avoid us. So even for people with no spiritual beliefs, it is important to have a peaceful mind.
