Upanishadene

Upanishadene, known in English as the Upanishads, are a collection of ancient Indian philosophical and mystical texts that form the concluding portion of the Vedas. The name derives from Sanskrit and means “sitting near [the teacher],” referencing the traditional guru–student setting in which knowledge was transmitted. The Upanishads are central to Vedanta, the interpretive tradition that seeks to articulate the Vedic worldview in metaphysical terms.

Dating and scope: The texts were composed and compiled over many centuries, broadly from around 800 BCE to 200 CE, with earlier layers possibly older. They exist in numerous recensions and in several Vedic schools, and a traditional count speaks of 108 Upanishads, though a core group of principal Upanishads is most widely read. Notable examples include Isa, Kena, Katha, Mundaka, Mandukya, Chandogya, Brihadaranyaka, Prasna, Taittiriya, and Shvetashvatara.

Content and influence: The Upanishads explore questions about the nature of ultimate reality (Brahman), the self (Atman), and the means to liberation (moksha). They employ dialogues, aphorisms, and contemplative narration, often emphasizing meditation, ethical living, and discernment. A key insight found in several texts is the unity of Atman and Brahman, summarized in statements such as tat tvam asi. Over time, the Upanishads profoundly influenced Hindu philosophy, giving birth to various Vedanta schools (Advaita, Vishishtadvaita, Dvaita) and shaping devotional and meditation practices. They also influenced later religious and philosophical thought in and beyond India, through commentaries and translations.
