It may be recalled that a marga directly consists of normative rules (sadhana-vidhi) for the attainment of ends but presupposes a body of descriptive rules (siddhanta, tattva) establishing causal connections between means and ends and also at least a working conception of desirable ends and generally available means.
Despite their basis in rational and supra-rational knowledge respectively, the formulated systems of niti and dharma are relative to historically given conditions. This is proved by the fact that although both were originally revealed by Rsabha, their socially current tradition changed in course of time and had to be renewed.While in the case of lokottara dharma the essence as comprehended by the kevalin remains unchanged, the actual tradition as remembered and practised does undergo change through corruption as after Bharata or through forgetfulness as after Mahavira.

Hemcandra, takes for granted the technical elements which had been formulated in the earlier tradition. He mentions them but does not describe them in detail. This helps to save his work from reedless repetition Of the offices of the state he describes those of the counseller, the military chief and the ambassador as the most important. The king as a sovereign is the linchpin of the state. The counsellor represents the whole apparatus of council and assistance, spreading out into the administrative system. The military commander signifies the organisation of defence and offence. The ambassador is the prime instrument of diplomacy. These four, sovereignty, administration,
