Manduka Upanishad, he gave the highest non-dual message of the identity of Atman and Brahman.+

The whole wisdom of Sage Sankara can be summed up in the following statement:-

Brahma satyam, jaganmithya, jivobrahmaivanaparah: ~Brahman alone is real; the world is non-real and the individual ‘Self’ is essentially not different from Brahman.

This is the quintessence of Sage Sankara’s wisdom.

Sage Sankara gave out what was of most use to the greatest number of people. Therefore, in the commentaries on the Upanishads, such as the famous Manduka Upanishad, he gave the highest non-dual message of the identity of Atman and Brahman, revitalizing the philosophy and practice of Advaita, while in the commentaries on the Brahmasūtra he gave lesser teaching, positing both higher and lower Maya and higher and lower Brahman (Ishvara) to explain creation for those of lesser intellects until they were ready for the highest truth.

The misinterpretation is because of Bhagavan Buddha himself’. Most of the questions were answered only by silence leaving many to interpret as per their understanding. The enlightenment of Bhagavan Buddha and which again was indirectly accepted by Sage Goudpada. : ~ Santthosh Kumaar
