Although what people consider Morality to be changes from society to society, we prefer to focus on what will bring about harmlessness in our actions, speech and thoughts. That is, we focus on developing Compassion/Lovingkindness, Sympathetic Joy and Equanimity; these Unselfish Emotions help us to develop much more unselfish speech and actions. In Buddhist terms, Morality includes Right Intention, Right Speech, Right Action, and Right Livelihood.
We manifest these unselfish emotions in the world in our actions and speech; by bringing compassionate awareness to our speech and actions and trying to purify them so that they are harmless to ourselves and harmless to others is a large part of the practice. The Buddha gave a guideline to undertake the rules of training: to abstain from killing living beings, to abstain from false speech, to abstain from wrong conduct in sexual relations, to refrain from taking what is not given, and to abstain from intoxicants that confuse the mind. These training rules enable us to show compassion to ourselves, and helps to protect ourselves and protect others from harm.
So we like to focus more on bringing forth the qualities that enable us to have more Right Speech, more Right Action, and Right Livelihood. That is: the Compassion/Lovingkindness intention, and the other Unselfish Emotions, and supporting it with the wisdom to understand that everything we think, say and do has a result. As we see this within ourselves, we see that we don't get away from having responsibility for our actions, speech and thoughts. Through compassion to ourselves, we're careful about what we say and what we do, realizing that we're going to receive the results of it, now and in the future.
Examples on how we can improve it? It begins by developing an unselfish intention. That is, working harder on developing the unselfish emotions such as Compassion/Lovingkindness. Especially working harder on developing this Compassionate/Lovingkindness more throughout our daily life – to give a Compassion/Lovingkindness wish before we go into rooms, before we associate with people, etc. Sometimes, if we're clouded by what we have to do when we arrive at a place or what we have to say to these people or whatever, instead of having a compassionate, unselfish emotion before we meet them, we may fall into the eight worldly conditions - being concerned about getting their praise or blame, etc. So if we develop more of the capacity to use these compassionate, lovingkind wishes throughout our life, it's very helpful.
Another thing that will increase your capacity to be less harmful in your Morality is to understand the eight worldly conditions and let go of attachment to them. So again, learning how to reflect on the eight worldly conditions, and how they're so often not within our power to control, helps us focus again on our principles. And talking about principles, with Irena Sendler, she had a guideline within her mind about what human life was. Likewise, we have to look at our views and our values to see if they are in line with harmlessness. The Buddha talks about Right Intention as thoughts directed towards harmlessness, free from ill-will and cruelty. This is a very important.
