The Aranyakas (/ɑːˈrʌnjəkə/; Sanskrit: āraṇyakaआरण्यक) is the philosophy behind sacrifice of the ancient Hindu sacred texts, the Vedas. They are usually part of the later parts of Vedas, and are one of many layers of the Vedic text. The other parts of Vedas are the Samhitas (benedictions, hymns), Brahmanas (commentary), and the Upanishads (spirituality and abstract philosophy).
↑In post-Vedic classifications by text types, the Aranyakas are one of five, with other four being Samhita, Brahmana, Upasana and Upanishad; see A Bhattacharya (2006), Hindu Dharma: Introduction to Scriptures and Theology, ISBN978-0595384556, pages 5-17
