Shankaracharya’s Commentary on the Bhagavad Gita: Understanding His Advaita Vedanta

The Bhagavad Gita has been interpreted by generations of Indian philosophers, saints and scholars, but few commentaries have had as profound an influence as the Bhagavad Gita Bhashya of Adi Shankaracharya. Traditionally attributed to the 8th-century philosopher and teacher Adi Shankaracharya, this commentary presents the Gita through the philosophical vision of Advaita Vedanta, the doctrine of non-duality.

Shankaracharya does not treat the Gita merely as a book of moral advice or a guide to worldly success. He understands it as a spiritual teaching whose ultimate purpose is to remove ignorance about one’s true nature and reveal the identity of the individual Self, or Atman, with Brahman, the ultimate reality.

His commentary continues to be studied because it provides a systematic philosophical interpretation of Krishna’s dialogue with Arjuna.

Who Was Shankaracharya?

Adi Shankaracharya is traditionally regarded as one of the most influential teachers in the history of Indian philosophy. His teachings established and systematized the Advaita Vedanta interpretation of the Upanishads, Bhagavad Gita and Brahma Sutras.

The three are traditionally regarded as the Prasthana Traya, the three principal scriptural foundations of Vedanta.

Shankaracharya wrote commentaries on these foundational works, although the authorship of some texts traditionally attributed to him is debated by modern scholarship.

His central philosophical teaching is that ultimate reality is Brahman, pure consciousness that is not limited by individual identity, physical form or changing circumstances.

According to Advaita, human beings ordinarily mistake the temporary body, mind and personality for the true Self. This fundamental misunderstanding is called avidya, or ignorance.

The purpose of spiritual knowledge is to remove this ignorance.

Shankaracharya and the Bhagavad Gita

Shankaracharya’s Gita Bhashya is a verse-by-verse philosophical commentary on the Bhagavad Gita.

The Gita itself describes a conversation between Krishna and Arjuna on the battlefield of Kurukshetra. Arjuna becomes overwhelmed by doubt and grief before the battle, and Krishna gradually teaches him about duty, action, meditation, devotion and knowledge.

Shankaracharya sees this dialogue as ultimately leading toward liberating knowledge.

For him, the Gita’s teachings should not be understood as advocating action for its own sake. Rather, disciplined action can help prepare the mind for the higher knowledge through which liberation becomes possible.

This distinction is central to understanding his interpretation.

Karma Yoga as Preparation

One of the most important aspects of Shankaracharya’s interpretation concerns Karma Yoga, the disciplined performance of one’s duties without attachment to their results.

The Gita repeatedly teaches Arjuna to perform his duty while remaining detached from the fruits of action.

Shankaracharya gives this teaching an important place in spiritual development. Selfless action helps reduce selfish attachment and gradually purifies the mind.

However, in his Advaita interpretation, action itself does not produce liberation in the same way that knowledge does.

Why?

Because the fundamental problem is ignorance of one’s true nature.

If a person believes, “I am merely this body and individual personality,” the problem is fundamentally one of mistaken knowledge. Performing more actions does not directly remove that ignorance.

Knowledge does.

Karma Yoga therefore becomes a means of preparing the seeker for Jnana, or spiritual knowledge.

The Importance of Jnana

For Shankaracharya, Jnana Yoga occupies a central position in the Gita’s spiritual teaching.

Jnana means knowledge, but it is not simply intellectual information.

It refers to direct spiritual understanding of the Self and the ultimate nature of reality.

The ordinary individual identifies with the body, senses and mind. Advaita asks the seeker to investigate the deeper question:

Who am I?

The body changes. Thoughts change. Emotions change. Experiences come and go.

Yet there is an underlying consciousness through which these changes are known.

Shankaracharya’s interpretation directs the seeker toward recognizing this consciousness as the true Self.

Atman and Brahman

The heart of Advaita Vedanta is the relationship between Atman and Brahman.

At the highest level of spiritual realization, Shankaracharya teaches that the individual Self is not fundamentally separate from Brahman.

This does not mean that the ordinary personality is God in a simplistic sense.

Rather, Advaita distinguishes between the changing individual personality and the deeper Self that is pure consciousness.

The realization of this truth removes the fundamental ignorance that creates the perception of separateness.

This is why Shankaracharya reads many teachings of the Gita through the lens of non-duality.

What About Bhakti?

Shankaracharya’s philosophy is sometimes mistakenly presented as though it has no place for devotion.

That is too simplistic.

The Gita contains extensive teachings about devotion to Krishna, and Shankaracharya acknowledges the importance of devotion and worship within spiritual life.

However, his philosophical framework ultimately places devotion within a larger movement toward knowledge of ultimate reality.

For a seeker who has not yet realized non-duality, devotion to God can cultivate humility, concentration, purity and surrender.

Thus, devotion can become an important part of spiritual preparation.

At the highest level of Advaita, however, the distinction between worshipper and ultimate reality is transcended.

The Meaning of Renunciation

Another important feature of Shankaracharya’s commentary is his treatment of Sannyasa, or renunciation.

Renunciation does not simply mean abandoning society or physically leaving one’s home.

At a deeper level, renunciation concerns freedom from attachment and identification.

Shankaracharya emphasizes the importance of giving up attachment to the results of worldly activity.

For the seeker pursuing liberation, renunciation creates the conditions necessary for contemplation and Self-knowledge.

This helps explain why Shankaracharya places considerable emphasis on the relationship between Karma Yoga and Jnana Yoga.

Selfless action purifies the mind, while knowledge reveals the Self.

Liberation According to Shankaracharya

The ultimate goal of the Gita, in Shankaracharya’s Advaita interpretation, is Moksha, or liberation.

Moksha is not merely a heavenly reward after death.

It is freedom from ignorance and the mistaken identification of the Self with the limited individual personality.

When ignorance disappears, the true nature of the Self becomes apparent.

The liberated person recognizes that ultimate reality is not divided into countless independent selves.

This realization is described as freedom from the cycle of bondage and suffering.

Why His Commentary Remains Important

Shankaracharya’s Gita Bhashya remains important for several reasons.

First, it is one of the earliest major systematic commentaries on the Bhagavad Gita associated with the Advaita Vedanta tradition.

Second, it established a powerful philosophical framework through which generations of readers have approached Krishna’s teachings.

Third, it demonstrates how the Gita can be understood simultaneously as a practical spiritual guide and a profound philosophical text.

His interpretation also became an important foundation for later Advaita teachers and commentators.

Shankaracharya Compared With Other Vedanta Traditions

The Gita has never had only one philosophical interpretation.

Later Vedanta teachers developed different understandings of its teachings.

Ramanujacharya, for example, interpreted the Gita through Vishishtadvaita, or qualified non-dualism. His philosophy gives a distinctive place to devotion and the relationship between the individual soul and God.

Madhvacharya, meanwhile, developed the Dvaita or dualist interpretation, emphasizing an enduring distinction between God and individual souls.

Shankaracharya’s Advaita interpretation differs significantly from both.

Studying these commentaries together can therefore reveal the extraordinary philosophical diversity within the Indian tradition.

A Living Philosophical Text

The lasting importance of Shankaracharya’s commentary is not simply historical.

The questions addressed in the Gita remain deeply human: Who am I? What is my responsibility? Why do I suffer? What is freedom? What is permanent in a changing world? Is the individual truly separate from ultimate reality?

Shankaracharya’s answer is uncompromising: our deepest problem is ignorance of our true nature, and liberation comes through the removal of that ignorance.

His Gita commentary therefore turns the battlefield dialogue between Krishna and Arjuna into a profound inquiry into consciousness, identity, action and ultimate reality.

For anyone interested in Advaita Vedanta, the Bhagavad Gita Bhashya is one of the most significant texts to study. It does not merely explain Krishna’s words; it presents a complete philosophical vision of what those words mean for the search for liberation.

Conclusion

Shankaracharya’s commentary on the Bhagavad Gita occupies a remarkable place in Indian philosophical history. Through the lens of Advaita Vedanta, he presents Krishna’s teaching as a progressive spiritual path in which disciplined action, devotion and mental purification prepare the seeker for the highest knowledge.

At the center of his interpretation is the realization that the true Self is not the temporary body or personality but pure consciousness, ultimately non-different from Brahman.

For centuries, seekers have returned to this interpretation because it addresses one of the most fundamental questions of spiritual life: What is our true nature?

Shankaracharya’s answer forms the philosophical heart of Advaita Vedanta—and his Gita Bhashya remains one of the most important traditional gateways into that vision.
