The Brahmanas are Vedic śruti works attached to the Samhitas of the Rig, Sama, Yajur, and Atharva Vedas. They are a secondary layer or classification of Sanskrit texts embedded within each Veda, which explain and instruct on the performance of Vedic rituals. In addition to explaining the symbolism and meaning of the Samhitas, Brahmana literature also expounds scientific knowledge of the Vedic Period, including observational astronomy and, particularly in relation to altar construction, geometry. Divergent in nature, some Brahmanas also contain mystical and philosophical material that constitutes Aranyakas and Upanishads.

Sanskrit is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting effect on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies.
