Define Aranyaka.

Aranyaka, derived from the Sanskrit root "aranya," meaning "forest" or "wilderness," refers to a distinct category of ancient Indian texts associated with the Vedic tradition. Aranyakas are part of the Vedas and are often considered a transitional genre between the ritualistic Samhitas and Brahmanas and the speculative Upanishads.

Aranyakas are characterized by their contemplative and philosophical nature, often composed in seclusion within forest settings. These texts are associated with the third segment of the Vedic ritual known as the "forest-dwelling" or "vanaprastha" stage of life.

In the Aranyakas, rituals and sacrificial practices are elaborated upon with a greater emphasis on symbolic interpretations, mysticism, and meditative aspects. They serve as a bridge between the external, ritualistic aspects of the Vedic tradition and the more introspective, speculative insights found in the Upanishads.

While the Samhitas and Brahmanas focus on the external dimensions of Vedic rituals and ceremonies, the Aranyakas introduce a more contemplative and symbolic dimension, setting the stage for the profound metaphysical inquiries that characterize the Upanishads. Aranyakas, therefore, play a crucial role in the evolution of Vedic thought from ritualistic practices to the deeper exploration of philosophical and spiritual themes.
