Shankara Advaita Vedanta: The Philosophy of Non-Dual Reality

Shankara’s Advaita Vedanta is the most influential system of non-dual metaphysics in Indian history, declaring that Brahman alone is real, the world of multiplicity is an appearance, and the individual self (Atman) is none other than Brahman. Adi Shankara, an eighth-century philosopher from Kaladi, Kerala, composed commentaries on the Upanishads, the Bhagavad Gita, and the Brahma Sutras that would shape Hindu thought for over a millennium. His system is not merely a philosophical position but a path to liberation: the direct recognition that the bondage you feel is the result of a single misperception, and that when that misperception is removed by knowledge, what remains is the recognition that you were never bound. In one line: Shankara’s Advaita teaches that the Self you seek is what you already are—infinite, eternal, and one with the ground of all existence.

Part 1: The Core Philosophy

Brahman Alone Is Real

The foundational declaration of Shankara’s Advaita is that Brahman alone is real. Brahman is the one underlying reality of the universe—infinite, eternal, unchanging, and beyond all attributes. It is described as Sat-Chit-Ananda—existence, consciousness, and bliss. According to Advaita Vedanta, God or Brahman is identical with the inner self (the Atman) of each person, while the rest of the world is nothing but objective illusion (maya).

Shankara maintains that there are two primary levels of existence and knowledge: the higher knowledge that is Brahman itself, and the relative, limited knowledge, regarded as the very texture of the universe. Consequently, the task of a human being is to reach the absolute unity and the reality of Brahman—in other words, to reach the innermost self within his or her own being, discarding on the way all temporary characteristics and attributes.

The Two Aspects of Brahman

Shankara distinguishes between Nirguna Brahman—Brahman without attributes, the ultimate reality—and Saguna Brahman—Brahman with attributes, the personal God, Ishvara. Saguna Brahman is a personal being designated by the pronoun He. The Being without attributes now is seen to possess infinite attributes. The unfathomable First Cause becomes an object of worship. Saguna Brahman is called Ishvara and is worshipped by the devout as Brahma the Creator, Vishnu the Preserver, and Shiva the Destroyer. But Ishvara and his appearances are real only from the lower point of view. The man who has attained the higher point of view knows that fundamentally and ultimately only Nirguna Brahman exists.

Shankara’s distinction between levels of reality allows him to retain a theism that involves serious religious intent. Ishvara is Brahman associated not with a limited mind and body like the jiva, but with maya, the universal creative matrix, the divine energy that projects the entire cosmos. Unlike the jiva, the Lord is not taken in by the delusive, concealing power of maya. The jiva is controlled by maya; Ishvara is the controller of maya.

The World Is an Appearance

The world of multiplicity that we perceive is not ultimately real. It is an appearance, a projection of Maya, the power of Brahman that causes the One to appear as many. Shankara distinguishes three levels of being or reality: pratibhashika-satta (illusory reality, such as hallucinations and mirages), vyavaharika-satta (the everyday empirical world), and paramarthika-satta (ultimate reality, identified with Brahman).

The world has empirical reality as long as one has not realized the ultimate truth. Within this empirical reality, external objects are quite as real as the cognitions we have of them. The world is not exactly illusory, for it is constantly present to the experience of all jivas. This ontologically indeterminate mode of being is characterized as sad-asad-anirvachaniya—”inexpressible as either real or unreal.”

Atman Is Brahman

The individual soul (Jiva) is not different from Brahman. Its apparent individuality is due to Avidya—ignorance of its true nature. The Mahavakyas (great sayings) declare this identity. The first statement identifies the objective universe with Brahman; the second statement (“I am Brahman”) identifies the individual with Brahman. The exact manner in which the objective universe is held to be identical with Brahman and the individual subject is held to be identical with Brahman are not identical.

The jiva is described as “that of a complex, and points not only to an element which is identical with Brahman, but also to limiting adjuncts like ‘the internal organs’.” The empirical reality about the jiva consists of the fact that it is caught up in the process of samsara, bound by its karma.

Part 2: The Nature of Liberation

Jivanmukti – Liberation While Living

According to the Advaita school, one can have liberation from samsara even when alive. The one who attains this is called a Jivanmukta—liberated while living. The Jivanmukta continues to live and act in the world but is no longer bound by it.

Adi Shankara explains that nothing can induce one to act who has no desire of his own to satisfy. The supreme limit of vairagya (“detachment”) is the non-springing of vasanas in respect of enjoyable objects; the non-springing of the sense of the “I” in things which are the anatman is the extreme limit of bodha (“awakening”); and the non-springing again of the modifications which have ceased is the extreme limit of uparati (“abstinence”). The Jivanmukta, by reason of his ever being Brahman, is freed from awareness of external objects and no longer aware of any difference between the inner atman and Brahman and between Brahman and the world, ever experiencing infinite consciousness.

“There is no samsara as before for one who has known Brahman.”

The Three Kinds of Prarabdha Karma

There are three kinds of prarabdha karma (karma bearing fruit in this life): Ichha (“personally desired”), Anichha (“without desire”), and Parechha (“due to others’ desire”). For a self-realized person, a Jivanmukta, there is no Ichha-Prarabdha but the two others, Anichha and Parechha, remain, which even a Jivanmukta has to undergo. According to the Advaita school, for those of wisdom, Prarabdha is liquidated only by experience of its effects; Sancita (“accumulated karmas”) and Agami (“future karmas”) are destroyed in the fire of Jnana (“knowledge”).

Videhamukti – Liberation Without the Body

When the body falls away, the Jivanmukta becomes a Videhamukta—liberated without the body. Vidyaranya puts a different interpretation on the concept of videhamukti. He grants that normally the expression refers to deliverance without relation to any form of embodiment. But he uses it to denote merely the absence of future embodiment. The acquisition of right knowledge, he argues, is intended only to ward off future embodiment. The body in which the saving knowledge is won is the product of past acts; it was there before the dawn of that knowledge and so its origin could not have been prevented by that knowledge.

Indeed, the function of knowledge is not to destroy any body; it only abolishes nescience. Therefore, Vidyaranya concludes that Videhamukti must be taken to mean deliverance with the certainty that no future embodiment awaits the Self.

Part 3: The Path to Liberation

Knowledge Alone Liberates

For Shankara, Jnana (knowledge) is the direct and immediate means of liberation. Action and knowledge are contradictory and poles apart. Actions are prescribed for those who are still in ignorance and not for the enlightened. Shankara emphatically asserts that liberation can be attained by the Supreme knowledge accompanied with the renunciation of action.

The higher kind of Moksha known as absolute liberation is attained by the knowledge of one’s perfect identity with Para-Brahman (Higher Brahman). The soul that attains this kind of liberation is called a Jivanmukta (one that has attained liberation during this life on earth). To attain this kind of liberation, no Karma (or fulfilment of duties) can serve as the direct means. Jnana or Knowledge of Reality alone leads to this absolute liberation.

The Fourfold Qualification (Sadhana Chatushtaya)

The tradition lists four qualifications that prepare the seeker for Self-knowledge. The Vedanta Sara of Sri Swami Sadananda enumerates the sadhana-chatushtaya:

1. Viveka (Discrimination): “Discrimination between things permanent and transient consists of the discernment that ‘Brahman alone is permanent and that all things other than It are transient’.”
2. Vairagya (Dispassion): Renunciation of the enjoyment of the fruits of actions in this world and hereafter.
3. Shat-Sampat (The Six Treasures): The six wealths such as control of the mind, control of the external senses, etc.
4. Mumukshutva (Desire for Liberation): An intense, burning desire for liberation.

The Vedantic tradition truly and firmly insists that only if an aspirant has the above four-fold means in full measure can he attain the knowledge of Truth.

The Role of the Guru

Since the realization of the Self cannot be had from books or scriptures, Shankara insists on the necessity of instruction by a Self-realized Guru. The intense desire to liberate and the effort required by the sadhaka (aspirant) is emphasized. If there is no effort, there cannot be a result.

Part 4: Shankara’s Legacy

The Organizational Structure

Shankara purportedly established the earliest monastic system in Brahmanical religion, including the Dasanami (Ten Names) renouncer orders as well as four or five principal monasteries (mathas) across the subcontinent. Many Shankara-identifying lineages, along with the principal monasteries, continue to flourish today in the living Advaita Vedanta tradition.

The Living Tradition

An unbroken lineage beginning with Shankara’s direct disciples, such as Padmapada and Sureshvara, continued to develop, defend, and expand upon his philosophy into the modern period. At present, Shankara’s Advaita Vedanta extends far beyond its orthodox cultural and geographical confines. Its streams of thought continue to evolve due to the encounter with different philosophical, theological, and socio-political contexts; yet the tradition as a whole demonstrates a significant degree of philosophical continuity from past to present.

Common Questions

Q1: What is Shankara’s Advaita Vedanta?
Advaita Vedanta is the non-dualistic school of Indian philosophy systematized by Adi Shankara. It teaches that Brahman alone is real, the world of multiplicity is an appearance, and the individual self (Atman) is none other than Brahman.

Q2: What are the two aspects of Brahman?
Shankara distinguishes between Nirguna Brahman (without attributes), the ultimate reality, and Saguna Brahman (with attributes), the personal God Ishvara. Saguna Brahman is real only from the lower point of view; from the higher point of view, only Nirguna Brahman exists.

Q3: What is Maya?
Maya is the power of Brahman that causes the One to appear as many. It is not illusion in the sense of being nothing; it is illusion in the sense of being an appearance that conceals the underlying reality.

Q4: What is Jivanmukti?
Jivanmukti is liberation while living. The one who attains it is called a Jivanmukta. According to Advaita, one can have liberation from samsara even when alive.

Q5: What is the path to liberation?
For Shankara, Jnana (knowledge) is the direct and immediate means of liberation. The path involves the fourfold qualification (discrimination, dispassion, the six treasures, and desire for liberation), study of the scriptures under a qualified guru, and the direct realization of one’s identity with Brahman.

Summary

Shankara’s Advaita Vedanta is the most influential system of non-dual metaphysics in Indian history. It declares that Brahman alone is real, the world of multiplicity is an appearance, and the individual self (Atman) is none other than Brahman. Shankara systematized this teaching through his commentaries on the Upanishads, the Bhagavad Gita, and the Brahma Sutras, and he established monastic centers to preserve and propagate the tradition. His philosophy emphasizes the prime necessity of Jnana (knowledge) for liberation, while allowing a place for Karma and Bhakti as preparatory disciplines. The path involves the fourfold qualification, study of the scriptures under a qualified guru, and the direct realization of one’s identity with Brahman. That realization—that the Self you seek is what you already are—is the gift of Shankara’s Advaita Vedanta.
