Upanishads

The Upanishads are a vast corpus of philosophical and contemplative texts that form the concluding essence of the Vedas, which is why they are also known as Vedanta ("the end of the Veda"). Composed in Sanskrit over several centuries, the Upanishads contain the deepest reflections of the ancient sages (rishis) on the nature of ultimate reality (Brahman), the identity of the individual soul (atma), and the relationship between them. Over two hundred Upanishads exist, although thirteen are traditionally recognized as the principal ones, including the Ishopanishad, the Chandogya, the Brihadaranyaka, and the Katha. Each Indian philosophical school interprets them differently. Monistic (advaita) currents emphasize the absolute identity of the soul and Brahman, while theistic Vaishnava schools underscore the eternal distinction between the soul and Bhagavan, along with the supremacy of personal devotion (bhakti). In Gaudiya Vaishnavism, the Upanishads are studied as revealed scriptures (sruti) that, when correctly interpreted, confirm the personal nature of the Supreme Truth and the constitutional position of the soul as the eternal servant of Krishna. Their study illuminates the philosophical understanding that sustains daily devotional practice.
