This is the Path By Ajahn Dtun
From the book: This is the Path
When we have mindfulness and wisdom, we can see the harm there is in acting in unskillful ways and doing things which transgress the precepts. In keeping the five precepts, always maintaining them in one’s daily life, one will come to see the benefit of the precepts. Within the heart of each person there has to be a moral conscience, along with a fear and dread of the consequences of one’s unwholesome actions.
The maintaining of the five precepts is considered as being a quality of a consummate human being. People who do not keep the five precepts can be considered as not being truly human, since the least humans can do is to keep these precepts. When we have this sense of moral conscience and a dread of the consequences of our actions, it truly elevates our minds – it is like having the mind of a devata, or a celestial being. And when we wish to further develop and cultivate our minds, we should then practice the Brahma Vihāras, or the four sublime states, nurturing them in our hearts: firstly, having mettā or loving kindness; secondly, karunā or compassion; thirdly, muditā or sympathetic joy; fourthly, upekkhā or equanimity. All these are the states of mind or properties of a Brahma.
Having loving kindness, mettā, means that we have friendliness and kindness towards our friends as well as all living beings, not wishing to harm or hurt them, or to take the life of any being.
Compassion, karunā, is the quality that arises when we see other people, animals or any kind of beings experiencing suffering. If we are able to help them, we try to do so with the best of our ability, according to our level of mindfulness and wisdom. This means that we have an attitude of kindness and the wish to help one another.
The quality of sympathetic joy, muditā, means that if we see any person experiencing happiness, we as a consequence, are happy for them. We feel happy too, having no envy or jealousy for the happy person, because in reality we all wish for happiness and so when we see other people experiencing happiness, we are happy for them and feel pleasure too.
As for the quality of equanimity, upekkhā, if we see other beings or animals experiencing suffering or hardship and we are unable to be of assistance, we must then let the mind rest with equanimity by feeling neither happy nor unhappy with the situation.
