Swaraj lays stress on governance, not by a hierarchical government, but by self governance through individuals and community building. The focus is on political decentralisation. Since this is against the political and social systems followed by Britain, Gandhi's concept of Swaraj advocated India's discarding British political, economic, bureaucratic, legal, military, and educational institutions.
