It is in everybody's interest to seek those [actions] that lead to happiness and avoid those which lead to suffering. And because our interests are inextricably linked, we are compelled to accept ethics as the indispensable interface between my desire to be happy and yours.
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.
I believe that the basic nature of human beings is gentle and compassionate. It is therefore in our own interest to encourage that nature, to make it live within us, to leave room for it to develop. If on the contrary we use violence, it is as if we voluntarily obstruct the positive side of human nature and prevent its evolution.
An affectionate disposition not only makes the mind more peaceful
and calm, but it affects our body in a positive way too. On the
other hand, hatred, jealousy and fear upset our peace of mind, make
us agitated and affect our body adversely. Even our body needs peace
of mind and is not suited to agitation. This shows that an
appreciation for peace of mind is in our blood.
Too much of a self-centered attitude creates mistrust and suspicion in others, which can in turn lead to fear. But if you have more of an open mind, and you cultivate a sense of concern for others' well-being, then, no matter what others' attitudes are, you can keep your inner peace.
Whether we consider the individual, family, local, national or international level, peace must arise from inner peace. For example, making prayers for peace while continuing to harbor anger is futile. Training the mind and overcoming your anger is much more effective than mere prayer. Anger, hatred and jealousy never solve problems, only affection, concern and respect can do that.
The motivation of all religious practice is similar: love, sincerity, honesty. The way of life of practically all religious persons is consistent. The teachings of tolerance, love, and compassion are the same.
In the past, the respect people had for religion meant that ethical practice was maintained through a majority following one religion or another. But this is no longer the case. We must therefore find some other way of establishing basic ethical principles.
Without religion, also there is a way, it could be this way, through education, through scientific findings, then you get conviction. Not necessarily really love other, but for their own interest they are showing love, compassion to other like that.
