notes
The Upanishads (Sanskrit: "sitting down near" — a student sitting at the feet of a teacher) are a collection of philosophical texts forming the end of the Vedic corpus. Of the 108 texts traditionally counted, thirteen are considered the principal Upanishads and have shaped all subsequent Indian philosophy. Composed between approximately 800 and 200 BCE, they mark a decisive turn in Indian religious thought: away from the external ritual of the Vedas toward internal contemplation of the self (atman) and its identity with the cosmic absolute (Brahman). The central teaching, expressed in the Chandogya Upanishad as "Tat tvam asi" (That art thou), is that the individual self and the ultimate reality are identical — a radical equation that dissolves the boundary between the individual and the cosmos. The Upanishads form the basis of Vedanta philosophy, and through it, of Hinduism as it has been practiced for two millennia. Translation after F. Max Müller, Sacred Books of the East, Vols. 1 and 15 (1879–1884). Public domain.
