How did belief in process of reincarnation provide a justification for this sysmtem?

Belief in reincarnation provided a justification for social hierarchies, particularly in systems like the Caste System in India, by suggesting that individuals' current circumstances are a result of their actions in previous lives. This idea fostered acceptance of one's social status, as it was seen as a consequence of past deeds, encouraging people to fulfill their duties within their assigned roles. Consequently, it promoted social stability and discouraged rebellion against the established order, reinforcing the notion that spiritual progress could only be achieved through adherence to one's caste responsibilities.
