What are the key differences between Shruti and Smriti texts in Hinduism?

Shruti texts in Hinduism are considered to be divinely revealed and are considered authoritative and unchanging, while Smriti texts are considered to be human-authored and can be updated or revised. Shruti texts include the Vedas and Upanishads, while Smriti texts include the epics like the Mahabharata and Ramayana, as well as the Puranas and Dharmashastras.
