Shandilya Upanishad Explained: A Detailed Guide to the Eightfold Path of Yoga and the Knowledge of Brahman

Short Answer
The Shandilya Upanishad is a detailed Yoga Upanishad attached to the Atharvaveda that presents a comprehensive guide to the eight-limbed path of yoga (ashtanga yoga) as the means to attain the true Self (Atman) and realize Brahman. Its title is derived from the sage Shandilya, who questions the divine teacher Atharvan about the path to liberation. The text is among the most detailed in the Upanishadic corpus on yoga techniques, describing ten yamas (restraints), ten niyamas (observances), eight asanas (postures), three pranayamas, five pratyaharas, five kinds of dharana, two types of dhyana, and one samadhi. The first chapter is one of the most comprehensive Upanishadic treatises on various types of yoga. The last two chapters integrate Advaita Vedanta philosophy, particularly the non-dual Nirguna Brahman as the ultimate Self, and assert the oneness of Atman in all living beings. The Upanishad emphasizes the necessity of both yoga (practice) and jnana (knowledge) for liberation.

In one line: The Shandilya Upanishad is a comprehensive manual of yoga that combines detailed ashtanga practice with the non-dual knowledge of Brahman.

Part 1: What Is the Shandilya Upanishad? Name, Origins, and Classification

The Name and Its Meaning

The title “Shandilya” is derived from the name of the sage Shandilya (Śāṇḍilya), who is the student receiving the teaching in the dialogue. The text is also known as the Shandilya Yoga Sutras in some traditions and is listed as number 58 in the Muktika canon of 108 Upanishads. In the anthology of Upanishads by Narayana, it appears at number 103. The text is also known as the Shandilyopanishad in some manuscripts. It is closely related to the Shandilya Vidya, a famous meditation from the Chandogya Upanishad, but it is a distinct text dedicated primarily to yoga.

Classification and Vedic Affiliation

The Shandilya Upanishad is one of the 20 Yoga Upanishads, a group of texts that focus on the practical path of yoga as a means to liberation. It is attached to the Atharvaveda. The text is also among the 31 Upanishads associated with the Atharvaveda. It is structured into three chapters with multiple sections in each. The first chapter deals with Ashtanga Yoga and contains eleven sections covering Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana, and Samadhi. The second chapter is a shorter exposition of Brahma Vidya (knowledge of Brahman). The third chapter discusses the nature and forms of Brahman: Sakala Brahman, Niskala Brahman, and Sakala-Niskala Brahman.

Date and Historical Context

The chronology of the Shandilya Upanishad is uncertain, but it is generally placed between 100 BCE and 300 CE. Some scholars, like Roy Eugene Davis, suggest it may pre-date Patanjali’s Yogasutras, while others, like Georg Feuerstein, argue it probably post-dates them. Thomas McEvilley states that the text was likely composed around the time of the Dhyanabindu Upanishad and before the Hatha Yoga Pradipika. The text is considered one of the most detailed in the Upanishadic corpus on yoga techniques.

Part 2: The Opening – Shandilya’s Inquiry and the Eight-Limbed Path

The Dialogue Between Shandilya and Atharvan

The Upanishad opens with the sage Shandilya approaching the divine teacher Atharvan and asking:

“Please tell me about the eight angas (limbs) of yoga which are the means of attaining to Atman.”

Atharvan replies:

“The eight angas of yoga are yama, niyama, asana, pranayama, pratyahara, dharana, dhyana and samadhi. Of these, yama (restraints) is of ten kinds; and so is niyama (observances). There are eight asanas (yoga postures). Pranayama (breath control) is of three kinds; pratyahara (sense withdrawal) is of five kinds; so also is dharana (concentration). Dhyana (contemplation) is of two kinds and samadhi (Realization) is of one kind only.”

The Expanded Yamas (Ten Restraints)

The Shandilya Upanishad presents an expanded list of ten Yamas (ethical restraints):

Yama	Meaning
Ahimsa	Not causing pain to any living being at any time through mind, speech, or body
Satya	Speaking truth that conduces to the well-being of creatures through mind, speech, or body

The Expanded Niyamas (Ten Observances)

The ten Niyamas are:

Tapas	Austerity through penances
Santosha	Contentment with whatever comes
Astikya	Faith in the merits or demerits of actions as stated in the Vedas
Dana	Giving lawfully earned money, grains, etc., to deserving persons

Part 3: The Subtle Body – Nadis, Vayus, Chakras, and Kundalini

The Fourteen Nadis and Ten Vayus

A significant portion of the first chapter is dedicated to the subtle anatomy of the body. The text describes the fourteen main nadis (energy channels) through which prana flows. The methods of purifying the nadis are described in great detail, as purification is considered necessary for the higher stages of concentration and meditation. The text also describes the ten vayus (vital airs), the manipura chakra, and the kundalini of the subtle body.

The Awakening of Kundalini

The Upanishad describes the practice of awakening Kundalini:

“Having by contraction opened the door of kundalini, one should force open the door of moksha. Closing with her mouth the door through which one ought to go, the kundalini sleeps spiral in form and coiled up like a serpent. He who causes this kundalini to move—he is an emancipated person. If this kundalini were to sleep in the upper part of the neck of any yogin, it goes towards his emancipation. Leaving the two nadis, Ida and Pingala, it should move in the Sushumna. That is the supreme seat of Vishnu.”

The Purification of Nadis

The text provides detailed instructions on the purification of the nadis through pranayama techniques. This purification is considered necessary for the higher stages of concentration and meditation. The text also describes the practice of khechari mudra and Vaishnavi mudra, control of prana, awakening kundalini, and the practice of samyama.

Part 4: Pranayama, Pratyahara, Dharana, Dhyana, and Samadhi

Pranayama

The text describes three types of pranayama (breath control). It defines pranayama as AUM, and provides detailed instructions on the practice of nadi shodhana pranayama with emphasis on kumbhaka (breath retention) and its effects. The text also describes the means of stopping the fluctuations of prana through various methods, including the closing of the uvula with the tongue, the movement of prana through the upper hole, and the calming of the eye of consciousness.

Pratyahara

Pratyahara is described as the withdrawal of the senses from external objects. The text lists five types of pratyahara, though the specific types are not detailed in the surviving fragments.

Dharana and Dhyana

The text describes five kinds of dharana (concentration) and two types of dhyana (meditation). Dhyana is the continuous flow of thought toward a single object. The text emphasizes the necessity of both yoga and jnana for liberation.

Samadhi

Samadhi is described as the final stage of yoga, where the mind becomes completely absorbed in the object of meditation. The text describes one kind of samadhi, which is the culmination of the eight-limbed path.

Part 5: The Second Chapter – Brahma Vidya

The second chapter of the Shandilya Upanishad is a shorter section that expounds Brahma Vidya—the knowledge of Brahman. It contains sections on the knowledge of Brahman, the creation of the universe, and the names of Brahman. The chapter also mentions the sage Dattatreya, the embodiment of the Avadhuta tradition. This chapter marks the transition from the practical yoga of chapter one to the philosophical knowledge of chapter three.

Part 6: The Third Chapter – The Threefold Nature of Brahman

Sakala, Niskala, and Sakala-Niskala Brahman

The third chapter discusses the nature and forms of Brahman, presenting three aspects:

Form	Meaning	Description
Sakala Brahman	Brahman with attributes	The manifest, qualified Brahman, worshipped in form
Niskala Brahman	Brahman without attributes	The unmanifest, attributeless, non-dual Brahman
Sakala-Niskala Brahman	Both	The integration of both aspects, representing the highest truth

The text integrates the Advaita Vedanta philosophy, particularly the “nondual Nirguna Brahman as the ultimate self” concept of Hinduism. It asserts that there is oneness of Atman in all living beings and that everything is Brahman.

The Teaching of Shandilya

The Upanishad includes the teaching of Shandilya himself, which is identical to the famous Shandilya Vidya from the Chandogya Upanishad:

“This great Being whose actions are all actions, whose desires are all desires, whose functions are all functions through the senses, is inside me and It is that which is inside everything.”

Part 7: Further Exploration with Dr. Surabhi Solanki’s Books

For readers inspired by the profound teachings of the Shandilya Upanishad and the path of yoga and Self-knowledge, Dr. Surabhi Solanki’s books offer an excellent contemporary gateway. A physician and spiritual thinker from Uttarakhand, Dr. Solanki bridges classical Advaita Vedanta with modern clarity and psychological insight.

Awakening Through Vedanta: Timeless Wisdom of Adi Shankaracharya serves as an accessible guide to the non-dual philosophy that the Shandilya Upanishad teaches—the identity of the individual Self with Brahman and the path to liberation through knowledge. Bhagavad Gita: Insights from Adi Shankaracharya explores the nature of action, knowledge, and devotion, complementing the Upanishad’s integration of yoga and jnana. Essence of Yoga Vasista: The Book of Liberation offers wisdom on dissolving the mind-demon of desire and living a life of freedom, resonating with the Upanishad’s teachings on the path of yoga. Divine Truth Unveiled: Hidden Secrets of Gaudapada’s Mandukya Karika offers a luminous guide to the Upanishadic foundations of Advaita, including the analysis of consciousness.
