The Isha Upanishad (ईशोपनिषद्) is one of the shortest Upanishads, embedded as the final chapter (adhyāya) of the Shukla Yajurveda. The Upanishad is a brief poem, consisting of 17 or 18 verses, depending on the recension. It is a key scripture of the Vedanta sub-schools and an influential Śruti to diverse schools of Hinduism. It is the 40th chapter of Yajurveda. The name of the text derives from its incipit, īśā vāsyam, “enveloped by the Lord”, or “hidden in the Lord (Self)”. The text discusses the Atman (Self) theory of Hinduism and is referenced by both Dvaita (dualism) and Advaita (non-dualism) sub-schools of Vedanta. It is classified as a “poetic Upanishad” along with Kena, Katha, Svetasvatara, and Mundaka by Paul Deussen (1908).

Isha Upanishad Meaning

The root of the word Ishvara comes from īś- (ईश, Ish) which means “capable of” and “owner, ruler, chief of”, ultimately cognate with English own. The word Isha (ईश) literally means “ruler, master, lord”. The term vāsyam (वास्य) literally means “hidden in, covered with, enveloped by”. Ralph Griffith and Max Muller, each interpret the term “Isha” in the Upanishad interchangeably as “Lord” and “Self” (one’s Self). Puqun Li translates the title of the Upanishad as “the ruler of the Self”. The Upanishad is also known as Ishavasya Upanishad and Vajasaneyi Samhita Upanishad.

Chronology of Isha Upanishad

The chronology of Isha Upanishad, along with other Vedic-era literature, is unclear and contested by scholars. All opinions rest on scanty evidence, assumptions about the likely evolution of ideas, and presumptions about which philosophy might have influenced which other Indian philosophies.

Buddhism scholars

Buddhism scholars such as Richard King date Isha Upanishad’s composition roughly to the second half of the first millennium BC, chronologically placing it after the first Buddhist Pali canons.

Hinduism scholars

Hinduism scholars such as Stephen Phillips note the disagreement between modern scholars. Phillips suggests that Isha Upanishad was likely one of the earliest Upanishads, composed in the 1st half of the 1st millennium BCE, after Brihadaranyaka and Chandogya, but before Taittiriya, Aitareya, Kaushitaki, Kena, Katha, Manduka, Prasna, Svetasvatara, and Maitri Upanishads, as well as before the earliest Buddhist Pali and Jaina canons.

Earlier 19th- and 20th-century scholars have similarly expressed a spectrum of views. Isha Upanishad has been chronologically listed by them as being among the early Upanishads to being one among the middle Upanishads. Deussen suggested, for example, that Isha was composed after ancient prose Upanishads – Brihadaranyaka, Chandogya, Taittiriya, Aitareya, Kaushitaki, and Kena; during a period when metrical poem-like Upanishads were being composed. Further, he suggests that Isha was composed before other prose Upanishads such as Prasna, Maitri, Mandukya, and all post-Vedic era Upanishads.

Winternitz’s suggestion

Winternitz, suggests that Isha Upanishad was probably a pre-Buddha composition along with Katha, Svetasvatara, Mundaka, and Prasna Upanishad, but after the first phase of ancient Upanishads that were composed in prose such as Brihadaranyaka, Chandogya, Taittiriya, Aitareya, Kaushitaki, and Kena. Winternitz states that Isha was likely composed before post-Buddhist Upanishads such as Maitri and Mandukya.

Ranade posits that Isha was composed in the second group of Upanishads along with Kena Upanishad, right after the first group of Brihadaranyaka and Chandogya, but chronologically before Taittiriya, Aitareya, Kaushitaki, Katha, Mundaka, Svetasvatara, Prasna, Mandukya, and Maitrayani.

Isha Upanishad Structure

Isha Upanishad is the only Upanishad that is attached to a Samhita, the most ancient layer of Vedic text known for its mantras and benedictions. Other Upanishads are attached to a later layer of Vedic texts such as Brahmanas and Aranyakas. Max Muller notes that this does not necessarily mean that Isha Upanishad is among the oldest, because Shukla Yajur Veda is acknowledged to be of a later origin than textual layers of other Vedas such as the Rigveda.

The 8th-century Indian scholar Adi Shankara, in his Bhasya (review and commentary), noted that the mantras and hymns of Isha Upanishad are not used in rituals, because their purpose is to enlighten the reader as to “what is the nature of Self (Atman)?”; the Upanishad, thus, despite Yajurveda Samhita’s liturgical focus, has not historically served as a liturgical text. Isha Upanishad is a philosophical text.

Difference between recensions

The Isha Upanishad manuscript differs from the two shakhas of the Shukla Yajurveda. These are called the Kanva (VSK) and Madhyandina (VSM) recensions. The order of verses 1–8 is the same in both, however, Kanva verses 9–14 correspond to Madhyandina verses 12, 13, 14, 9, 10, 11. Madhyandina verse 17 is a variation of Kanva 15, Kanva verse 16 is missing in Madhyandina, and Kanva verses 17–18 correspond to Madhyandina 15–16.

In both recensions, the Isha Upanishad is the 40th chapter of Shukla Yajurveda. Versions with 18 verses refer to Kanva, while those with 17 verses are referring to the Madhyandina.

Isha Upanishad Content

Monism versus theism

The Isha Upanishad is significant for its singular mention of the term “Isha” in the first hymn, a term it never repeats in other hymns. The concept “Isha” exhibits monism in one interpretation, or a form of monotheism in an alternative interpretation, referred to as “Self” or “Deity Lord” respectively.

Enveloped by the Lord must be This All — each thing that moves on earth. With that renounced, enjoy thyself. Covet no wealth of any man. — Isha Upanishad, Hymn 1

Ralph Griffith interprets the word “Isha” contextually, translates it as “the Lord”, and clarifies that this “the Lord” means “the Self of All, and thy inmost Self – the only Absolute Reality”. The term “This All” is the empirical reality, while the term “renounced” is referring the Indian concept of sannyasa, and “enjoy thyself” is referring to the “blissful delight of Self-realization”.

Pursuit of Karma versus Pursuit of Self

The Isha Upanishad, in hymns 2–6, acknowledges the contrasting tension within Hinduism, between the empirical life of householder and action (karma) and the spiritual life of renunciation and knowledge (jnana).

Should one wish to live a hundred years on this earth, he should live doing Karma. While thus, as man, you live, there is no way other than this by which Karma will not cling to you. Those who partake the nature of the Asuras [evil], are enveloped in blind darkness, and that is where they reside who ignore their Atman [Self]. For liberation, know your Atman, which is motionless yet faster than mind, it is distant, it is near, it is within all, it is without all this. It is all pervading. And he who beholds all beings in the Self, and the Self in all beings, he never turns away from it [the Self]. — Isha Upanishad, Hymns 2-6

Adi Shankara suggests that “he” in hymn 6 (last sentence in the above quote) is the “seeker of emancipation, on a journey to realize Self and Oneness in innermost self and everyone, and includes those in sannyasa”; while Madhvacharya suggests “he” is “the individual Self in loving devotion of God, seeking to get infinitely close to the God Self”.

Avidya

The Isha Upanishad suggests that one root of sorrow and suffering is considering one’s Self as distinct and conflicted with the Self of others, assuming that the nature of existence is a conflicted duality where one’s happiness and suffering is viewed as different from another living being’s happiness and suffering. Such sorrow and suffering cannot exist, suggests the Upanishad, if an individual realizes that the Self is in all things, understands the Oneness in all of existence, focuses beyond individual egos, and in the pursuit of Universal values, the Self and Real Knowledge.

When to a man who understands,
the Self has become all things,
what sorrow, what trouble can there be,
to him who beholds that unity. — Isha Upanishad, Hymn 7

The Isha Upanishad, in hymns 8 through 11, praises the study of Vidya (Real Knowledge, eternal truths) and Avidya (not Real Knowledge, empirical truths). It asserts that to he who knows both Vidya and Avidya, Avidya empowers him to overcome death (makes one alive), while Vidya empowers him with immortality. Real Knowledge delivers one to freedom, liberation from all sorrows and fears, to a blissful state of life. Mukherjee states that Isha Upanishad in verse 11 is recommending that one must pursue material knowledge and spiritual wisdom simultaneously and that a fulfilling life results from the harmonious, balanced alignment of the individual and the social interests, the personal and the organizational goals, the material and the spiritual pursuits of life.

Virtue versus vice

In final hymns 15 through 18, the Upanishad asserts a longing for Knowledge, asserting that it is hidden behind the golden disc of light, but a light that one seeks. It reminds one’s own mind to remember one’s deeds and accept their consequences. 

The Madhyandina recension and Kanva recension vary in relative sequencing of the hymns, but both assert the introspective precept, “O Agni (fire) and mind, lead me towards a life of virtues, guide me away from a life of vices”, and thus unto the good path and the enjoyment of wealth (of both karma‘s honey and Self-realization). The final hymns of Isha Upanishad also declare the foundational premise, “I am He”, equating one Self’s oneness with the cosmic Self.

पुरुषः सोऽहमस्मि
I am He, the Purusha within thee. — Isha Upanishad, Hymn 16 Abridged

Isha Upanishad Reception

Mahatma Gandhi thought so highly of it that he remarked, “If all the Upanishads and all the other scriptures happened all of a sudden to be reduced to ashes, and if only the first verse in the Ishopanishad were left in the memory of the Hindus, Hinduism would live forever.” Paul Deussen states that the first verses are notable for including the ethics of one who knows the Ātman.

Isha Upanishad: A Compilation Of 18 Verses

Isha Upanishad is a compilation of a total of 18 verses. Let us understand how and what these Isha Upanishad verses try to explain:

Verse 1

First and Foremost, just in the initial stage, the Upanishad explains how everything on the earth and in this universe is transitory. Thus, all of the things in the world can be labeled as relatively real or illusory. It focuses on showcasing the importance of anything that moves on the earth, all those things that can seem to be real should be covered with the lord., an indwelling self. You can manifest all things in motion on this earth and thus know the importance of self-worth. The only reality or truth according to Isha Upanishad is acquired when the soul realizes its world of name and form, and thereby also renounces what can be said to be worldly desires like son, wealth, and worlds. Thus, realize your true nature of self through determination and renunciation.

The world is not something you should abandon but is to be lived in by being attached to wealth in any form and thus, accepting that wealth is illusory. The Real-world is our self-dwelling and doesn’t entail giving up on the attachment. The first verse is meant for those who fit the ideal candidate of renouncing desire through knowledge. And for those, who can grasp this knowledge, the second verse imparts instruction on how to handle the situation.

Verse 2

By the following karma, one should be able to live a life on this earth for a hundred years. For an individual who follows such rules and lifestyles. There is no other way to do this. Here karma will always stay by your side.

The person who has not yet attained the true knowledge of the lead life can engage himself in the life of karma which is joined by the Vedas. Most of us can not actually differentiate our actions from our human attachments. Thus, karma can actually help us to sharpen our sense of reasoning and discrimination and thereby help us purify our minds.

Verse 3

This verse of the Isha Upanishad warns us about negating the principle. It states that anyone who tries to defy the principle will be thrown into utter darkness, wherein the individual will suffer through the worldly life and thus, as an atonement, the wisdom will shine upon him.

Verse 4

As we discussed earlier, the concept of Atman is an unmoving entity and thereby transcends all that is moving. It works faster than the mind or any senses and it is upon the Atman to project the actions of any individual. Ataman is an unmoving entity and thus, prevails everywhere, leaving no space for itself to move.

Verses 5, 6, 7

Where we understand how Atman pervades at the beginning of Verse 5, we can see how verse 6 and 7 talks about how the world is viewed and how it is perceived with respect to others. It also explains in detail how he can not reject or can not have a passion geared towards the world as it is the atman and everything is just a part of it.

Verse 8

The pursuit of knowledge and karma are two important things in attaining immortality. Both are necessary and thus, pursuing one will lead you to pursue the other. While one tries to practice karma and oversee death can aspire to attain immortality. Thus, we can say that both need to go together to reach their destination.

As the nature of Brahman is a stable one, it is faster than the mind. The senses can not overtake it. It is already present when the mind tries to reach it. Only an infinite entity that is stationary and pervasive can qualify itself to become the self or the Atman.

Verses 9,10,11

Avidya

It is a theoretical grasp of Self without sincere and honest efforts to realize the self Avidya on the other end is to take delusory experiences perceived through true senses. Avidya binds people with the illusory world. Through the knowledge of Avidya, a person comes to realize how they want to go further. Most of us are ignorant about higher knowledge, but an illuminated person can help you out of love as he elaborates on the concept of truth and honesty.

Vidya

Vidya is the knowledge that leads an individual toward realizing his goal. However, the people under the veil of Vidua are difficult to convince due to their nature of ignorance. 

Under these false senses of achievement, they might even go teaching and reaching others. They will also start behaving like they have realized the truth. These individuals without even going through the hardships of life, traditions, rituals, and practices delude themselves into harming the belief and notions of others. 

Verses 12, 13, 14

We can separate from the seer and the seen. This can help you set right the combination of karma and knowledge in your duties in the world. Thus, an individual can meet the objective of the world with supreme consciousness and meditation. These are some of the central offerings of knowledge through Isha Upanishad.

There are two kinds of practices to achieve liberation which are being discussed here. One includes escaping karma by combining it with knowledge and the second one is freeing yourself from dispassion and discrimination. Both of these practices help the mind to firmly fix oneself in the supreme consciousness.

Verses 15, 16, 17, 18

In these verses, Isha Upanishad describes how out of compassion and love for all, an individual arrays and reveals his true nature of the Lord. 

If an individual gives us into the enticement, They can never liberate themselves from this world. In this set of verses, It is also implied that the Purusha pervades in all and is attached to worldly attachments. This will give you pleasure as well as suffering.

Isha Upanishad Teachings

The first teaching of Isha Upanishad

Do not develop an attachment to the objects or pleasures in the world. Treat these objects only as a means for higher use.” Noteworthy here for the path of Sadhana is that the Ishopanishad defines “piety” on the basis of love and desirelessness, and “sin” on the basis of jealousy and selfishness.

Upanishadic scriptures say that man may perform all lawful actions, but only in the spirit of detachment.

Second teaching of Isha Upanishad

The so-called pangs of death are what one suffers who runs after worldly enjoyments and who, deeply attached to the objects of the world, does not want to relinquish “his” possessions. Death, in fact, is a pleasant thing; but those who are ignorant of its secret and of the true art of life have to suffer acute pain on account of attachment. It is not death, but the attachment that causes pain. Thus the thought of death is more painful than death itself.

Why shouldn’t death be as natural as birth? 

Death is inevitable and in it self-pleasant; that is why it occurs. Birth and death are necessary for every life.

Third teaching of Isha Upanishad

The third teaching is “Do not covet; let there be no greed.” Often seen on the path of Sadhana as in ordinary life, is the tendency, when something obstructs our path, to start blaming fate, providence, and God. When a trifle makes us grieved, we may turn our face against the right path.

We do not try to understand that the cause of restlessness is most frequently our own greedy nature. That is why the sadhaka should remain aloof from greed and acquisitiveness.

Fourth teaching of Isha Upanishad

The fourth teaching of the first three mantras of the Ishopanishad is “She wife, wealth and property as all belonging to God. Use them as means for the realization of God.” Great unhappiness flows from the attempt to protect our own wealth, rights, and property and to seize that of others.

The sadhaka should keep only so much in his possession as is needed for this life’s journey toward the Supreme Goal.

Fifth teaching of Isha Upanishad

The fifth teaching is “Always perform your duties, ever doing so with an attitude of disinterestedness, that is, without desire for personal reward. If a man wishes to live a hundred years, he should live thus performing duties and going toward the supreme goal.”

This mantra throws a challenge to seekers in all the ways, for it asserts that disinterested action is a pure, easy, and permitted path that may be and ought to be, followed by all.

Sixth teaching of Isha Upanishad

The sixth teaching of the first part of the Ishopanishad is “Always think, speak, and act according to the dictates of conscience and the call of the higher Self. The voice of conscience is the voice of the higher Self. Action performed against conscience amount to self-murder.

The soul in its very nature is pure, holy, and untainted by any flaw or impurity. Though he knows it to be wrong, man acts against conscience due to his lack of self-discipline. Such behavior is self-delusion, for in this manner no one can improve his moral and spiritual character and attain the goal of life. Spiritual progress is only possible through self-discipline and Sadhana.

Conscience is the mainspring of character formation. Without character, man cannot get entry into the spiritual world.

Seventh teaching of Isha Upanishad

The seventh teaching is “Do not slay your higher Self by selfishness, sensuality, and lack of Sadhana, otherwise, you will descend to lower states here and hereafter. According to the third mantra of the first part of the Ishopanishad, they are demons who perform actions in an immoral, selfish, and egotistical manner and have a deep attachment to the enjoyment of the senses.

By subduing their soul and suppressing the voice of conscience, they bring about their own downfall and find peace neither here in this world nor hereafter in other worlds.
