This scholarly publication presents the first chapter of Badarayana's Brahma Sutra, the समन्वयाध्याय (Samanvayādhyāya), which establishes the Upanishads as a valid source of knowledge about Brahman. The work begins with Shankara's famous introduction on अध्यास (Adhyāsa), or superimposition, setting the stage for his non-dualistic philosophy. Accompanied by the classic "Bhamati" commentary, this edition is an indispensable resource for anyone undertaking a serious study of Advaita Vedanta.
