Read the following passage and answer the questions :

A government in a democratic country has to respond to on-going priorities in public criticism and political reproach, and to the threats to survival it has to face. The removal of long standing deprivations of’ the disadvantaged people of our country may, in effect, be hampered by the biases in political pressure, in particular when the bulk of the social agitation is dominated by new problems that generate immediate and noisy discontent among the middle class Indians with a voice. If the politically active threats are concentrated only on some specific new issues, no matter how important (such as high prices of consumer goods for the relatively rich, or the fear that India’s political sovereignty might be compromised by its nuclear deal with the USA), rather than on the terrible general inheritance of India of acute deprivation, deficient schooling, lack of medical attention for the poor, and extraordinary under nourishment (especially of children and also of young women), then the pressure on democratic governance acts relentlessly towards giving priority to only those particular new issues, rather than to the gigantic persistent deprivations that are at the root of so much inequity and injustice in India. The perspective of realization of justice and that of an adequately broad nyaya are central not only to the theory of justice, but also to the practice of democracy.

What does the author mean by nyaya ?
