One often sees dharma translated as religion, duty, or even righteousness, but in fact, there is no single direct translation for dharma. Religion, duty and righteousness are not wrong; they are simply included within the idea of dharma. The word "dharma" comes from the Sanskrit root dhri, meaning to "uphold" or to "sustain." From this perspective, the best way to think of dharma is to say, "that which upholds or sustains the positive order of things: the nation, the community, the family and ultimately even the universe." At a social level, every individual has a particular dharma according to their place in life. Children have a dharma, parents have a dharma, teachers have a dharma, the police have a dharma and even the head of a nation has a dharma. One of the dharmas of a child, for example, is to obey parents and to study. Parents have a dharma to protect and look after children: to make sure they are educated, fed, housed and trained. It is sometimes written on the sides of police cars: To Serve and to Protect. This is a statement of dharma for police.
