I think there's every reason this 21st century will be much happier.

The need for love lies at the very foundation of human existence.

All major religious traditions carry basically the same message, that is love, compassion and forgiveness the important thing is they should be part of our daily lives.

In Buddhism, both learning and practice are extremely important, and they must go hand in hand. Without knowledge, just to rely on faith, faith, and more faith is good but not sufficient. So the intellectual part must definitely be present. At the same time, strictly intellectual development without faith and practice, is also of no use. It is necessary to combine knowledge born from study with sincere practice in our daily lives. These two must go together.

If the mind is dominated by hatred, the best part of the brain, which is used to judge right and wrong, does not function properly.

We all want to live a happy life and have a right to do so, whether through work or spiritual practice. I'm subject to destructive emotions like anger and jealousy the same as you, but we all have potential for good too. However, our existing education system is oriented towards material development; neglecting inner values. Consequently we lack a clear awareness of the inner values that are the basis of a happy life.

If science proves some belief of Buddhism wrong, then Buddhism will have to change.
