Note:- Advaita Sadguru Brahmasri Yallamraju Srinivasa Rao Garu first started his teachings with the Upanishads. Many people say that it is enough to listen to the essence of the Upanishads without listening to the Dasho Upanishads. The Guru said that one does not qualify to listen to the Brahma Sutras and Bhagavad Gita without listening to the Upanishads. Those who have the opportunity but cannot listen to the prophecies of the Upanishads are unfortunate. The Guru taught that those who are new to Advaita Vedanta should start listening to the Upanishads.
