Step-by-step explanation:
The ideas expressed in this passage from the Rigveda most directly contributed to the development of caste system in ancient Indian society. The passage describes the division of Purusha, a primordial being, into different parts that are associated with different social groups in society. For example, the Brahmins were thought to have emerged from Purusha's mouth, while the Rajanyas (warriors) originated from his arms.
