Like anyone else, I too have the potential for violence; I too have anger in me. However, I try to recall that anger is a destructive emotion. I remind myself that scientists now say that anger is bad for our health; it eats into our immune system. So, anger destroys our peace of mind and our physical health. We shouldn’t welcome it or think of it as natural or as a friend.
If you have a great deal of knowledge, but you're governed by negative emotions, then you tend to use your knowledge in negative ways. Therefore, while you are learning, don't forget the importance of warmheartedness.
Our visit to this planet is short, so we should use our time meaningfully, which we can do by helping others wherever possible. And if we cannot help others, at least we should try not to create pain and suffering for them.
The antidote to hatred in the heart, the source of violence, is tolerance. Tolerance is an important virtue of bodhisattvas [enlightened heroes and heroines] - it enables you to refrain from reacting angrily to the harm inflicted on you by others. You could call this practice "inner disarmament," in that a well-developed tolerance makes you free from the compulsion to counterattack. For the same reason, we also call tolerance the "best armor," since it protects you from being conquered by hatred itself.
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 most important thing is practice in daily life; then you can
know gradually the true value of religion. Doctrine is not meant for
mere knowledge, but for the improvement of our minds. In order to do
that, it must be part of our life. If you put religious doctrine in
a building and when you leave the building depart from the practices,
you cannot gain its value.
It may seem unrealistic to think we can ever become free from hatred, but Buddhists have systematic methods for gradually developing a tolerance powerful enough to give such freedom.
Developing inner values is much like physical exercise. The more we train our abilities, the stronger they become. The difference is that, unlike the body, when it comes to training the mind, there is no limit to how far we can go.
