Collections of poems, songs, and stories that form the core of Hindu beliefs. What is this called?

Hindu texts are manuscripts and historic literature related to any of the diverse traditions within Hinduism. A few texts are shared resources across these traditions and broadly considered as Hindu scriptures.[1][2] These include the Vedas and the Upanishads. Scholars hesitate in defining the term "Hindu scripture" given the diverse nature of Hinduism,[2][3] many include Bhagavad Gita and Agamas as Hindu scriptures,[2][3][4] while Dominic Goodall includes Bhagavata Purana and Yajnavalkya Smriti to the list of Hindu scriptures.[2]
