Bhagavad Gita 2.20 declares that the soul (Atman) is eternal, unborn, and imperishable—it is never born and never dies, and it is not slain when the body is slain. This verse is one of the most important declarations of the soul’s immortality in all of Hindu scripture. It is quoted almost verbatim from the Katha Upanishad (2.18/1.2.18), establishing its authority as shruti (revealed scripture) . Krishna delivers this teaching to Arjuna on the battlefield of Kurukshetra to dispel his grief over the prospect of killing his relatives. The verse does not merely offer comfort; it presents a precise metaphysical analysis of the soul’s nature, negating all six transformations that an impermanent entity undergoes. In one line: The soul is not the body; it is the unborn, eternal, and imperishable reality that death cannot touch.
Part 1: The Verse and Its Translation
The Sanskrit Verse
न जायते म्रियते वा कदाचित्
नायं भूत्वा भविता वा न भूयः।
अजो नित्यः शाश्वतोऽयं पुराणो
न हन्यते हन्यमाने शरीरे॥
na jāyate mriyate vā kadācit
nāyaṁ bhūtvā bhavitā vā na bhūyaḥ
ajo nityaḥ śāśvato ‘yaṁ purāṇo
na hanyate hanyamāne śarīre
The Translation
A standard translation reads:
“The soul is never born, nor does it ever die; nor having once existed, does it ever cease to be. The soul is unborn, eternal, ever-existing, and primeval. It is not slain when the body is slain.”
Ramanuja’s commentary offers a slightly different rendering:
“It (the self) is never born; It never dies; having come into being once, It never ceases to be. Unborn, eternal, abiding and primeval, It is not slain when the body is slain.”

Part 3: The Negation of the Six Transformations
The Six Modifications of Asat (the Impermanent)
The Advaita commentary explains that anything that is asat (impermanent, unreal in the ultimate sense) undergoes six transformations (ṣaḍ-vikāra) :
| Transformation | Sanskrit | Meaning |
|---|---|---|
| Birth | Jāyate | It is born |
| Existence | Asti | It continues to exist |
| Growth | Vardhate | It grows |
| Change | Vipariṇamate | It undergoes modifications |
| Decay | Apakṣīyate | It decays |
| Destruction | Vinaśyati | It is destroyed |
The Soul Is Beyond All Six
The verse systematically negates these transformations for the Self :
- By negating birth and death (na jāyate mriyate vā kadācit), the first and last transformations are denied.
- By stating “having come into being once, it never ceases to be” (nāyaṁ bhūtvā bhavitā vā na bhūyaḥ), the continuation of existence is affirmed and destruction is denied.
- By calling the Self “unborn” and “eternal” (ajaḥ nityaḥ), birth and death are negated.
- By calling it “everlasting” and “primeval” (śāśvataḥ purāṇaḥ), the remaining four transformations—growth, change, decay, and destruction—are negated.
The logic is precise: the Self is partless (niravayava) and attributeless (nirguṇa). An entity can undergo change only if it has parts that change or qualities that change. Since the Self has neither, it cannot grow, decay, or transform .
Part 4: The Two Readings of the Second Line
The Textual Variant
Some manuscripts read the second line as nāyaṁ bhūtvā abhavitā vā na bhūyaḥ—”Nor is it ever the case that having been existent, it becomes non-existent again” .
The Two Negations
The Advaita commentary explains that both readings serve the same purpose :
| Reading | Negates | Meaning |
|---|---|---|
| nāyaṁ bhūtvā bhavitā vā na bhūyaḥ | Birth | Anything that was non-existent and becomes existent is said to be born. This reading negates birth. |
| nāyaṁ bhūtvā abhavitā vā na bhūyaḥ | Death | Anything that was existent and becomes non-existent is said to die. This reading negates death. |
The Katha Upanishad supports both readings with its corresponding verse: nāyaṁ kutaścin na babhūva kaścit—”It is neither produced nor is something produced from it” .
Part 5: Ramanuja’s Commentary
The Context of Kalpa
Ramanuja’s commentary offers a distinctive interpretation. He explains that the statement “having come into being once, it never ceases to be” means that the Self, having emerged at the beginning of a Kalpa (aeon of manifestation), will not cease to be at the end of the Kalpa .
“This is the meaning—that birth at the beginning of the Kalpa in bodies such as those of Brahma and others, and death at the end of a Kalpa as stated in scriptures, do not touch the self.”
The Self as Ever-New
Ramanuja further explains that the Self is called purāṇaḥ (primeval) because “It existed from time immemorial; It is ever new i.e., It is capable of being experienced always as fresh” . This is a beautiful insight: the Self is not old and worn, but eternally fresh, always available to be experienced anew.
The Conclusion
Ramanuja concludes: “Therefore when the body is slain, the self is not slain” . The Self is untouched by the modifications of the body.
Part 6: The Katha Upanishad Connection
The Source Verse
Bhagavad Gita 2.20 is a direct quotation from the Katha Upanishad (2.18). The Katha Upanishad verse reads:
na jāyate mriyate vā vipaścin
nāyaṁ kutaścin na babhūva kaścit
ajo nityaḥ śāśvato ‘yaṁ purāṇo
na hanyate hanyamāne śarīre
The Gita’s version is nearly identical, with only minor variations. This establishes the Gita’s teaching as rooted in the Upanishadic revelation—not a new doctrine, but the eternal truth reaffirmed.
The Context in the Katha Upanishad
In the Katha Upanishad, this verse appears in the dialogue between Nachiketa and Yama, the Lord of Death. Nachiketa asks Yama about the nature of the soul after death. Yama responds with this verse, revealing that the soul is beyond birth and death entirely. The Gita places this same teaching in the mouth of Krishna, connecting the battlefield to the deepest metaphysical truth .
Part 7: The Practical Significance
Why This Verse Matters for Arjuna
Arjuna’s grief on the battlefield is rooted in the fear of killing his relatives. Krishna’s response in 2.20 addresses this fear directly: you cannot kill the soul. The body may be slain, but the Self is never slain. As the Times of India article explains: “If the soul cannot die, then death is not an ending but a change of form” .
The Metaphor of Worn-Out Clothes
Immediately after verse 2.20, Krishna offers the famous metaphor of worn-out clothes (2.22):
“Just as a person discards worn-out clothes and puts on new ones, the soul discards worn-out bodies and takes on new ones.”
This metaphor makes the abstract teaching concrete. The body is a garment. Death is simply the changing of clothes. The wearer—the Self—remains untouched.
The Foundation of Fearlessness
This teaching is the foundation of fearlessness. As one commentary notes: “When one is realised in this knowledge there is nothing which is going to trouble the person, because the real person inside the temporary bodily encagement can never be harmed under any circumstance” . The fear of death is the root of all other fears. When death is transcended, all fears dissolve.
Common Questions
Q1: Is this verse saying the soul is a “thing” that exists forever?
No. The soul is not a thing in the way objects are things. It is pure consciousness—the awareness that knows all things. It is called eternal because it is not subject to time, not because it persists through time like a long-lasting object.
Q2: If the soul is never born, how does it incarnate?
The soul does not “incarnate” in the sense of entering a body from outside. The soul is the consciousness that appears to be associated with a body due to ignorance. When the body dies, the soul does not go anywhere—it simply ceases to be associated with that particular body.
Q3: What is the difference between the soul and the body?
The body is perishable (śarīra), subject to birth, growth, decay, and death. The soul is imperishable (nitya), unborn, eternal, and unchanging. The body is an appearance in the soul, not the other way around.
Q4: How does Ramanuja’s commentary differ from Shankara’s?
Shankara interprets the verse from the standpoint of absolute non-duality: the Self is Brahman, and all birth and death are illusions. Ramanuja interprets it from the standpoint of qualified non-duality: the Self is eternal and distinct from the body, but it is a mode of Brahman, dependent on the Supreme .
Q5: Can I experience this truth, or is it only a belief?
The verse is not a belief to be accepted. It is a truth to be realized. The realization comes through discrimination (viveka) between the Self and the not-Self, and through the direct recognition of one’s own awareness as the unchanging witness of all experience.
Summary
Bhagavad Gita 2.20 declares the soul’s immortality with precision and authority. The soul is never born and never dies; it is unborn, eternal, everlasting, and primeval. It is not slain when the body is slain. The verse negates all six transformations of impermanent things—birth, existence, growth, change, decay, and destruction—revealing the Self as partless and attributeless, beyond all change. Quoted from the Katha Upanishad, it carries the authority of revealed scripture. Ramanuja explains it as teaching that the Self is ever-new, untouched by the births and deaths of bodies. That realization—that you are not the perishable body but the unborn, eternal, ever-fresh awareness that death cannot touch—is the gift of verse 2.20 and the foundation of fearlessness.
