Mandukya Upanishad and Gaudapada's Karika

The popular and often misunderstood Mandukya Upanishad is considered the “king” of the Upanishads because its simple, elegant logic in the hands of an accomplished teacher removes the belief that the Self is a finite entity, revealing its limitless fullness. The famous commentaries of Gaudapada, a great sage of the Vedantic sampradaya, presents a radical Creation teaching, non-origination. Creation teachings are important because the Upanishads unequivocally state that reality is non-dual consciousness/existence. If it is, then how can we explain the presence of duality, which we continually experience?
