If indeed the qualities such as love, patience, tolerance, and forgiveness are what happiness consists in, and if it is also true that compassion, defined as concern for others, is both the source and the fruit of these qualities, then the more we are compassionate, the more we provide for our own happiness.
Every human should have the idea of taking care of the environment, of nature, of water. So using too much or wasting water should have some kind of feeling or sense of concern. Some sort of responsibility and with that, a sense of discipline.
Many of the earth's habitats, animals, plants, insects and even micro-organisms that we know to be rare may not be known at all by future generations. We have the capability and the responsibility to act; we must do so before it is too late.
It is worthwhile for one to make an effort to achieve happiness. Just as the purpose of a plant is to grow, so it is that the main purpose of every human being is to survive and to grow until death.
Each of us in our own way can try to spread compassion into people's hearts. Western civilizations these days place great importance on filling the human brain with knowledge, but no one seems to care about filling the human heart with compassion. This is what the real role of religion is.
Every man has the basis of good. Not only human beings, you can find it among animals and insects, for instance, when we treat a dog or horse lovingly.
