Whether you believe in God or not does not matter much, whether you believe in Buddha or not does not matter so much; as a Buddhist, whether you believe in reincarnation or not does not matter so much. You must lead a good life.
It helps remove whatever fears or insecurities we may have and gives us the strength to cope with any obstacles we encounter. It is the principal source of success in life. Since we are not solely material creatures, it is a mistake to place all our hopes for happiness on external development alone. The key is to develop inner peace.
If science proves facts that conflict with Buddhist understanding, Buddhism must change accordingly. We should always adopt a view that accords with the facts.
There are many different kinds of power. True power comes from serving and helping others. Such behavior makes people respect you. They are willing to listen to your views and advice, and they support you. The energy of many people is thus channeled through one person. This kind of power is positive and authentic.
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.
Once we have a firm practice of compassion our state of mind becomes stronger which leads to inner peace, giving rise to self-confidence, which reduces fear. This makes for constructive members of the community. Self-centredness on the other hand leads to distance, suspicion, mistrust and loneliness, with unhappiness as the result.
"The true essence of humankind is kindness. There are other qualities which come from education or knowledge, but it is essential, if one wishes to be a genuine human being and impart satisfying meaning to one's existence, to have a good heart."
Genuine happiness consists in those spiritual qualities of love, compassion, patience, tolerance and forgiveness and so on. For it is these which provide both for our happiness and others happiness.
Our world is increasingly interdependent, but I wonder if we truly understand that our interdependent human community has to be compassionate; compassionate in our choice of goals, compassionate in our means of cooperation and our pursuit of these goals.
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.
