The Aranyakas (/ɑːˈrʌnjəkəz/; Sanskrit: आरण्यक; IAST: āraṇyaka) are a part of the ancient Indian Vedas concerned with the meaning of ritual sacrifice, composed in about 700 BC. They typically represent the later sections of the Vedas, and are one of many layers of Vedic texts. The other parts of the Vedas are the Samhitas (benedictions, hymns), Brahmanas (commentary), and the Upanishads (spirituality and abstract philosophy).
Aranyakas describe and discuss rituals from various perspectives; some include philosophical speculations. For example, the Katha Aranyaka discusses rituals connected with the Pravargya. The Aitareya Aranyaka includes explanation of the Mahavrata ritual from ritualisitic to symbolic meta-ritualistic points of view. Aranyakas, however, neither are homogeneous in content nor in structure. Aranyakas are sometimes identified as karma-kanda (कर्मकाण्ड), ritualistic action/sacrifice section, while the Upanishads are identified as jnana-kanda (ज्ञानकाण्ड) knowledge/spirituality section. In an alternate classification, the early part of Vedas are called Samhitas and the ritualistic commentary on the mantras and rituals are called the Brahmanas which together are identified as the ceremonial karma-kanda, while Aranyakas and Upanishads are referred to as the jnana-kanda.
