A person who does the things which are to be done and who doesn't do the things which are not to be done; a person who sticks to rational behaviour (or behaves rationally), is called "Arya".
The term "Arya" is used to refer to elder or respectable person in India. This subhashita give some of the characteristics of 'Arya'. A person who does the things which he is supposed to do i.e. good things, and does not do any bad, can be called Arya.. In short, the one who obeys dharma is Arya. 'Arya' does not reflect any race.
