Mandukya Upanishad Bhashya

Shankara's commentary argues that the self (Atman), analyzed through the four states of consciousness—waking (Vishva), dream (Taijasa), deep sleep (Prajna), and Turiya—is ultimately identical with Brahman. The bhashya rejects the view that Turiya is merely a fourth state alongside the other three; instead, Turiya is the witness consciousness that underlies and illumines all states while remaining untouched by them [citation:10][citation:27]. Shankara also rejects any dualistic reading of the Mandukya Upanishad, insisting that the Upanishad's declaration of non-duality (advaita) is the final truth. Following Gaudapada, he argues that the world of multiplicity is an appearance (mithya) superimposed on the non-dual reality, and that the highest teaching is ajativada—nothing is ever truly born [citation:10].

Unlike Shankara's commentaries on other Upanishads, his Mandukya Bhashya is not a standalone commentary on the twelve verses of the Upanishad alone. It comments on both the Upanishad and Gaudapada's four chapters of Karikas, which are traditionally appended to the Upanishad [citation:8][citation:10]. Gaudapada was Shankara's teacher's teacher, and the Karika is the foundational text of Advaita's philosophical articulation, particularly its doctrine of ajativada (non-origination) [citation:2][citation:11]. Shankara's bhashya thus serves to systematize and defend Gaudapada's teachings. This means that reading Shankara's Mandukya commentary without the Karika is impossible; the two are transmitted and studied as a single unit in the Advaita tradition.

Shankara explains that Turiya (the Fourth) is not a state of consciousness that comes and goes like waking, dreaming, or deep sleep. It is the witnessing awareness (sakshi) that is present in all three states but is itself never modified by them [citation:10][citation:27]. In waking, it illumines the external world; in dream, the internal world; in deep sleep, it illumines the absence of objects. Shankara emphasizes that Turiya is not to be attained or produced; it is the ever-present substratum of all experience, obscured only by ignorance (avidya). The Upanishad's identification of Turiya with AUM's silence, and with Atman, is interpreted by Shankara as the direct teaching of non-duality: the self is Brahman, and there is nothing other than it.

Shankara acknowledges that the Mandukya Upanishad and other scriptures speak of creation, but he follows Gaudapada in treating this as a provisional teaching (vyavaharika) intended for those who still perceive a world. The highest teaching (paramarthika) is ajativada: nothing is ever born [citation:10]. Shankara's method is to show that the language of creation is a concession to ignorance, not a description of ultimate reality. Just as a rope is mistaken for a snake in the dark, Brahman is mistaken for the world of multiplicity. When knowledge arises, the appearance is sublated, and only Brahman remains. This hierarchical hermeneutic allows Shankara to affirm the authority of scripture while denying that its creation narratives are literally true at the highest level of understanding.

The standard English translation for over a century has been that of Manilal N. Dvivedi, published in the Sacred Books of the East series (volume 15) and later reprinted by various publishers . This edition includes the Upanishad, Gaudapada's Karika, and Shankara's Bhashya, making it the most complete single-volume resource in English. Swami Gambhirananda's translation, published by Advaita Ashrama, is also widely used in the Ramakrishna Mission tradition. More recent translations include those by Swami Nikhilananda and Charles Johnston. For scholarly study, the Dvivedi edition remains essential because of its historical influence and its inclusion of the full Karika, which is indispensable for understanding Shankara's commentary.

The Mandukya Bhashya occupies a unique position in Shankara's corpus because of its dependence on Gaudapada's Karika. The Brahma Sutra Bhashya is Shankara's systematic exposition of Vedanta, engaging with rival schools and establishing the principles of Advaita interpretation. The Mandukya Bhashya, by contrast, is a focused analysis of consciousness and the self, working closely with Gaudapada's more radical formulations of ajativada [citation:8][citation:10]. While the Brahma Sutra Bhashya defends Advaita against dualist and Buddhist critiques, the Mandukya Bhashya explores the experiential dimensions of non-duality through the analysis of the four states. Together, they show Shankara working both as a systematic philosopher and as a commentator on the tradition's most profound psychological and metaphysical text.
