Kindness and a good heart are the foundation for success in this life, progress on the spiritual path, and the fulfillment of our aspirations. Our need for them is not limited to any specific time, place, society, or culture.
We must work to resolve conflicts in a spirit of reconciliation and always keep in mind the interests of others. We cannot destroy our neighours! We cannot ignore their interests!
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.
The compassion we feel normally is biased and mixed with attachment. Genuine compassion flows towards all living beings, particularly your enemies. If I try to develop compassion towards my enemy, it may not benefit him directly, he may not even be aware of it. But it will immediately benefit me by calming my mind. On the other hand, if I dwell on how awful everything is, I immediately lose my peace of mind.
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.
For discovering one's true inner nature, I think one should try to take out some time, with quiet and relaxation, to think more inwardly and to investigate the inner world. That may help.
With a basic understanding of all humans as brothers and sisters, we can appreciate the usefulness of different systems and ideologies that can accommodate different individuals and groups with different cultural heritages, having different dispositions and tastes. Each person has the right to choose whatever is most suitable, on the basis of a deep understanding of all others as brothers and sisters.
I have always had this view about the modern education system: we pay attention to brain development, but the development of warmheartedness we take for granted.
