Hindu texts are manuscripts and historical 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. These include the Vedas and the Upanishads. Scholars hesitate in defining the term "Hindu scripture" given the diverse nature of Hinduism, many include Bhagavad Gita and Agamas as Hindu scriptures, while Dominic Goodall includes Bhagavata Purana and Yajnavalkya Smriti to the list of Hindu scriptures.There are two historic classifications of Hindu texts: Shruti – that which is heard, and Smriti – that which is remembered. The Śruti refers to the body of most authoritative, ancient religious texts, believed to be eternal knowledge authored neither by human nor divine agent but transmitted by sages (rishis). These comprise the central canon of Hinduism. It includes the four Vedas including its four types of embedded texts - the Samhitas, the Brahmanas, the Aranyakas and the early Upanishads. Of the Shrutis (Vedic corpus), the Upanishads alone are widely influential among Hindus, considered scriptures par excellence of Hinduism, and their central ideas have continued to influence its thoughts and traditions.The Smriti texts are a specific body of Hindu texts attributed to an author, as a derivative work they are considered less authoritative than Sruti in Hinduism. The Smrti literature is a vast corpus of diverse texts, and includes but is not limited to Vedāngas, the Hindu epics, the Sutras and Shastras, the texts of Hindu philosophies, the Puranas, the Kāvya or poetical literature, the Bhasyas, and numerous Nibandhas (digests) covering politics, ethics, culture, arts and society.Many ancient and medieval Hindu texts were composed in Sanskrit, many others in regional Indian languages. In modern times, most ancient texts have been translated into other Indian languages and some in Western languages. Prior to the start of the common era, the Hindu texts were composed orally, then memorized and transmitted orally, from one generation to next, for more than a millennia before they were written down into manuscripts. This verbal tradition of preserving and transmitting Hindu texts, from one generation to next, continued into the modern era.
