<P> The Vedas (/ ˈveɪdəz /; Sanskrit: वेद veda, "knowledge") are a large body of knowledge texts originating in the ancient Indian subcontinent . Composed in Vedic Sanskrit, the texts constitute the oldest layer of Sanskrit literature and the oldest scriptures of Hinduism . Hindus consider the Vedas to be apauruṣeya, which means "not of a man, superhuman" and "impersonal, authorless". </P> <P> Vedas are also called śruti ("what is heard") literature, distinguishing them from other religious texts, which are called smṛti ("what is remembered"). The Veda, for orthodox Indian theologians, are considered revelations seen by ancient sages after intense meditation, and texts that have been more carefully preserved since ancient times . In the Hindu Epic the Mahabharata, the creation of Vedas is credited to Brahma . The Vedic hymns themselves assert that they were skillfully created by Rishis (sages), after inspired creativity, just as a carpenter builds a chariot . </P> <P> There are four Vedas: the Rigveda, the Yajurveda, the Samaveda and the Atharvaveda . Each Veda has been subclassified into four major text types--the Samhitas (mantras and benedictions), the Aranyakas (text on rituals, ceremonies, sacrifices and symbolic - sacrifices), the Brahmanas (commentaries on rituals, ceremonies and sacrifices), and the Upanishads (texts discussing meditation, philosophy and spiritual knowledge). Some scholars add a fifth category--the Upasanas (worship). </P> <P> The various Indian philosophies and denominations have taken differing positions on the Vedas . Schools of Indian philosophy which cite the Vedas as their scriptural authority are classified as "orthodox" (āstika). Other śramaṇa traditions, such as Lokayata, Carvaka, Ajivika, Buddhism and Jainism, which did not regard the Vedas as authorities, are referred to as "heterodox" or "non-orthodox" (nāstika) schools . Despite their differences, just like the texts of the śramaṇa traditions, the layers of texts in the Vedas discuss similar ideas and concepts . </P>
