Aranyaka is a term that has its roots in ancient Hinduism. It refers to a set of texts that are associated with forest tribes and hermits who lived in the Vedic period. The Aranyakas, along with the Vedas and Brahmanas, form the three main parts of the Vedic literature. This term can be synonymously referred to as "forest books" or "forest treatises." Another synonym for Aranyaka is "Aranyak," which is derived from the Sanskrit word "Aranya," which means "forest" or "wilderness." In addition, Aranyaka is sometimes synonymous with "Upanishads," which are spiritual texts that form the concluding part of the Vedas.
