It is the duty of a responsible king to protect the social and spiritual orders in human society. The spiritual orders are divided into four asramasbrahmacarya, grhastha, vanaprastha and sannyasaand the social orders, according to work and qualification, are made up of the brahmanas, the ksatriyas, the vaisyas and the sudras. These social orders, according to the different grades of work and qualification, are described in Bhagavad-gita. Unfortunately, for want of proper protection by responsible kings, the system of social and spiritual orders has now become a hereditary caste system. But this is not the actual system. Human society means that society which is making progress toward spiritual realization. The most advanced human society was known as arya; arya refers to those who are advancing. So the question is, Which society is advancing? Advancement does not mean creating material necessities unnecessarily and thus wasting human energy in aggravation over so-called material comforts. Real advancement is advancement toward spiritual realization, and the community which acted toward this end was known as the Aryan civilization. The intelligent men, the brahmanas, as exemplified by Kardama Muni, were engaged in advancing the spiritual cause, and ksatriyas like Emperor Svayambhuva used to rule the country and insure that all facilities for spiritual realization were nicely provided. It is the duty of the king to travel all over the country and see that everything is in order. Indian civilization on the basis of the four varnas and asramas deteriorated because of her dependency on foreigners, or those who did not follow the civilization of varnasrama. Thus the varnasrama system has now been degraded into the caste system.
