THE VEDIC PERIOD Samhitas.—The term veda, i.e. (sacred) "knowledge," "lore"— embraces a body of writings the origin of which is ascribed to divine revelation (fruti, literally "hearing"), and which forms the foundation of the Brahmanical system of religious belief. This sacred canon is divided into three or (according to a later scheme) four co-ordinate collections, likewise called Veda: (I) the Rig veda, or lore of praise (or hymns) ; (2) the Sama-veda, or lore of tunes (or chants) ; (3) the Yajur-veda, or lore of prayer (or sacri ficial formulas) ; and (4) the Atharva-veda, or lore of the Athar vans. Each of these four Vedas is a collection (samhitei) of sacred, mostly poetical, texts of a devotional nature, called mantra. This entire body of texts (and particularly the first three collections) is also known as the trayi vidya, or threefold wisdom, of hymn (rich), tune or chant (saman), and prayer (yajus)—the fourth Veda, when included, being classed together with the Rik.
had no special text-book assigned to him, but was expected to be familiar with all the Samhitas as well as with the practical details of the sacrificial performance. (See BRAHMAN and BRAH mmIA.) Brahmanas.—The several Samhitas have attached to them cer tain theological prose works, called Breihmana, which also form part of the canon. Their object is to explain the relationship of the Vedic texts to the now very elaborate sacrificial ceremonial and to explain their mystic import. (See BRAHMAN A.) Aranyakas and Upanishads.—Closely connected with the Brahmanas are two classes of treatises called Aratiyaka and Upanishad. The Aranyakas, i.e., works "relating to the forest," intended to be read or expounded by anchorites in the quiet of the forest, resemble the Brahmanas, which they supplement by dealing with special points of ritual. The Upanishads are of a more mystical nature, and form the first attempts at a systematic treatment of metaphysical questions. From their pantheistic views later developed the Vedanta philosophy. The Upanishads have to be assigned to very different periods of Sanskrit litera ture. The oldest treatises of this kind are doubtless those which form part of the Samhitas, Brahmanas and Aranyakas of the three older Vedas.
