Afflictive emotions - our jealousy, anger, hatred, fear - can be put to an end. When you realize that these emotions are only temporary, that they always pass on like clouds in the sky, you also realize they can ultimately be abandoned.
No matter what activity or practice we are pursuing, there isn't anything that isn't made easier through constant familiarity and training (I think you can apply this to soccer as well)
As long as we observe love for others and respect for their rights and dignity in our daily lives, then whether we are learned or unlearned, whether we believe in the Buddha or God, follow some religion or none at all, as long as we have compassion for others and conduct ourselves with restraint out of a sense of responsibility, there is no doubt we will be happy.
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. It is foolish to dwell on external differences, because our basic natures are the same.
Whether we like it or not, we have all been born into this world as part of one great human family. Rich or poor, educated or uneducated, belonging to one nation or another, to one religion or another, adhering to this ideology or that, ultimately each of is just a human being like everyone else. We all desire happiness and do not want suffering.
Lack of understanding of the true nature of happiness, it seems to me, is the principal reason why people inflict sufferings on others. They think either that the other's pain may somehow be a cause of happiness for themselves or that their own happiness is more important, regardless of what pain it may cause. But this is shortsighted. No one truly benefits from causing harm to another sentient being. . . . . In the long run causing others misery and infringing their rights to peace and happiness result in anxiety, fear, and suspicion within oneself.
Misunderstanding may arise by confusing the Buddhist and scientific definitions of death. Within the scientific system you spoke quite validly of the death of the brain and the death of heart. Different parts of the body can die separately. However, in the Buddhist system, the word death is not used in that way. You'd never speak of the death of a particular part of the body, but rather of the death of an entire person. When people say that a certain person died, we don't ask, "Well, which part died?"
It is lack of love for ourselves that inhibits our compassion toward others. If we make friends with ourselves, then there is no obstacle to opening our hearts and minds to others.
Hatred, jealousy and excessive attachment cause suffering and agitation. I feel compassion can help us overcome these disturbances and let us return to a calm state of mind. Compassion is not just being kind to your friend. That involves attachment because it is based on expectation. Compassion is when you do something good without any expectations - based on realizing that "the other person is also just like me".
What is important is to see how we can best lead a meaningful everyday life, how we can bring about peace and harmony in our minds, how we can help contribute to society.
We are beset by problems and if we look for their source, we find they arise because of our selfishness, because we tend to pursue our own interests at the expense of others. Our various religious traditions exist to help us reduce these problems. They all teach ways to overcome suffering through cultivating love and compassion, tolerance, patience and contentment.
