- Nature-Man-Spirit-Complex. (Answer in 150 words)
Introduction
The nature-man-spirit complex is L. P. Vidyarthi's formulation that tribal life forms one system in which habitat, community and the supernatural are not separable domains.

Body
1. What it asserts: the hill or forest is at once subsistence, residence and the abode of the deities, so economy, social organisation and religion form a single order; a change in one alters the others.
2. The setting: Vidyarthi framed it from his study of the Maler, the Sauria Paharia of the Rajmahal hills, published in 1963. Their slash-and-burn cultivation on hill slopes, their identification with the hill and their propitiation of the hill spirits supplied the model.
3. What it explains and its limits: it explains why tribal religion tracks the agricultural calendar, and why displacement destroys religion and society together — the argument behind habitat rights in the Forest Rights Act. It is criticised as descriptive rather than explanatory, assuming a closed equilibrium and having no account of market or state.

Conclusion
Its value is as a corrective to studying tribal religion apart from land — precisely the separation policy keeps making.
