श्रीभगवानुवाच।
काम एष क्रोध एष रजोगुणसमुद्भवः।
महाशनो महापाप्मा विद्ध्येनमिह वैरिणम्॥

śrī-bhagavān uvāca
kāma eṣa krodha eṣa rajo-guṇa-samudbhavaḥ
mahāśano mahā-pāpmā viddhy enam iha vairiṇam

"The Supreme Lord said: It is desire, it is anger, born of the quality of passion (rajas). It is all-devouring and all-sinful. Know this to be the enemy here."

— Bhagavad Gita 3.37

Introduction: The Question Behind the Answer

In the preceding verse, Arjuna asks one of the Gita's most psychologically acute questions: "By what is a person impelled to commit sin, even unwillingly, as if driven by force?" (3.36). We've all experienced this—knowing something is wrong, yet doing it anyway. What force compels us against our own better judgment?

Krishna's answer is direct and unsparing: it is desire (kama) and anger (krodha), born of the quality of passion. These are not minor obstacles but "the enemy"—the primary adversary in the soul's journey toward freedom. Understanding this verse deeply can transform how we relate to our own impulses and reactivity.

This teaching is particularly relevant in our modern age of constant stimulation and instant gratification. We are surrounded by triggers for desire and opportunities for anger. Social media, advertising, 24-hour news cycles—all feed the rajasic tendencies that the Gita identifies as our greatest obstacle. Understanding the mechanics of desire and anger is not just philosophical knowledge but practical wisdom for navigating contemporary life.

Word-by-Word Sanskrit Analysis

Every word in this compact verse carries weight. Let's examine each component:

🔤 Sanskrit Breakdown

श्रीभगवानुवाच (śrī-bhagavān uvāca) The Supreme Lord (śrī-bhagavān) said (uvāca); indicates the divine authority of the teaching
कामः (kāmaḥ) Desire, lust, craving; from the root "kam" meaning to wish or long for
एषः (eṣaḥ) This; demonstrative pronoun pointing directly to the culprit
क्रोधः (krodhaḥ) Anger, wrath; from the root "krudh" meaning to be angry
रजोगुण (rajo-guṇa) The quality of passion; one of three fundamental qualities of nature
समुद्भवः (samudbhavaḥ) Born from, arising from; indicates the origin or source
महाशनः (mahāśanaḥ) Great devourer, all-consuming; mahā (great) + aśana (eating/consuming)
महापाप्मा (mahā-pāpmā) Great sinner, all-sinful; the cause of great wrongdoing
विद्धि (viddhi) Know! (imperative); a command to understand deeply
एनम् (enam) This one; referring to desire/anger
इह (iha) Here, in this world; in this context of human life
वैरिणम् (vairiṇam) The enemy; from "vaira" meaning hostility or enmity

Note the emphatic repetition of "eṣaḥ" (this)—"It is THIS, it is THIS." Krishna points directly, eliminating any ambiguity. Note also the compound adjectives: "mahā-aśana" (great devourer), "mahā-pāpmā" (great sinner). These superlatives underscore the severity of the threat.

Context: Why This Teaching Now

Chapter 3 of the Gita is primarily about Karma Yoga—the yoga of action. Krishna has been explaining why action is necessary, why action without attachment leads to liberation, and how the wise perform action for the welfare of the world.

Arjuna, ever the practical student, raises the obvious objection: if action without attachment is the goal, what prevents us from achieving it? We know we should act without selfish motivation, but something keeps pulling us back into selfishness. What is that something?

अथ केन प्रयुक्तोऽयं पापं चरति पूरुषः।
अनिच्छन्नपि वार्ष्णेय बलादिव नियोजितः॥

"Arjuna said: But by what is a person impelled to commit sin, O Varshneya, even against their will, as if driven by force?"

Bhagavad Gita 3.36

This question reveals Arjuna's deep self-awareness. He recognizes that knowing what's right and doing what's right are different things. Something compels us toward wrong action "as if by force" (balād iva). Krishna's answer identifies that force: desire and its offspring, anger.

Kama: The Nature of Desire

The Sanskrit word "kāma" has a broader meaning than the English "desire." It includes:

  • Sensory desire: Craving for pleasurable experiences through the senses
  • Sexual desire: The procreative drive (though this is only one aspect)
  • Material desire: Wanting possessions, comfort, security
  • Psychological desire: Wanting recognition, approval, success
  • Existential desire: Wanting things to be other than they are

At its root, kama is the movement of consciousness toward objects, believing they will bring satisfaction. It's the fundamental "wanting" that drives human behavior—the sense that something out there will complete us if only we can obtain it.

The Mechanics of Desire

The Gita analyzes the mechanics of desire with remarkable precision:

ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते।
सङ्गात्सञ्जायते कामः कामात्क्रोधोऽभिजायते॥

"When a person dwells on sense objects, attachment to them arises. From attachment springs desire, and from desire comes anger."

Bhagavad Gita 2.62

The sequence is: attention (dhyāna) → attachment (saṅga) → desire (kāma) → anger (krodha). Desire doesn't arise from nowhere; it begins with where we place our attention. What we repeatedly think about, we become attached to. From attachment, desire naturally arises.

⚠️ The Trap of Desire

Desire promises satisfaction but never delivers permanently. Fulfilling one desire leads to more desires, not to contentment. Like drinking salt water to quench thirst, satisfying desire intensifies the underlying craving.

Krodha: The Nature of Anger

"Krodha" (anger) appears immediately after kama in the verse, and this juxtaposition is deliberate. Anger is not a separate problem but desire's shadow—what happens when desire is frustrated.

Anger as Frustrated Desire

Every anger, when traced to its root, reveals a thwarted desire:

  • We want respect and feel disrespected → anger
  • We want things to go our way and they don't → anger
  • We want peace and are disturbed → anger
  • We want love and feel rejected → anger
  • We want control and lose it → anger

Understanding this connection is transformative. When anger arises, we can ask: "What desire is being frustrated here?" This inquiry shifts us from reactive victim to curious observer, weakening anger's grip.

The Destructive Nature of Anger

The Gita continues its analysis:

क्रोधाद्भवति सम्मोहः सम्मोहात्स्मृतिविभ्रमः।
स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति॥

"From anger arises delusion; from delusion, confusion of memory; from confusion of memory, destruction of discrimination; from destruction of discrimination, one perishes."

Bhagavad Gita 2.63

This describes the downward spiral: anger → delusion (sammoha) → memory loss (smṛti-vibhrama) → loss of discrimination (buddhi-nāśa) → destruction (praṇaśyati). When angry, we lose our wisdom, forget our principles, and act in ways we later regret. The destruction of discrimination is particularly dangerous—we can no longer discern right from wrong.

The Connection: Desire Becomes Anger

Krishna identifies kama and krodha together because they are two phases of one energy. This insight is psychologically profound and practically useful.

The Transformation Process

  1. Desire arises: We want something—pleasure, recognition, success, love
  2. Obstacle appears: Something or someone blocks our desire
  3. Frustration builds: The energy of desire has nowhere to go
  4. Transformation occurs: Frustrated desire converts to anger
  5. Anger seeks outlet: The energy must discharge, often destructively

This explains why desire and anger are "one enemy" though they appear as two. Reducing desire automatically reduces anger, since there's less to be frustrated about. A person with few strong desires has little occasion for anger.

The Same Energy, Different Direction

Desire is energy moving toward an object; anger is energy moving against an obstacle. They're the same rajasic energy—passionate, restless, demanding—just directed differently. This is why the Gita targets both together: addressing the underlying rajas addresses both simultaneously.

Born of Rajas: The Passionate Quality

Krishna specifies that kama and krodha are "rajo-guṇa-samudbhavaḥ"—born from the quality of passion. Understanding the gunas illuminates why desire and anger are so powerful and persistent.

The Three Gunas

Vedic philosophy describes three fundamental qualities (gunas) that pervade all nature:

  • Sattva (goodness): Light, clarity, harmony, peace
  • Rajas (passion): Activity, desire, restlessness, ambition
  • Tamas (ignorance): Darkness, inertia, confusion, dullness

Rajas is the quality of movement and activity. It's necessary for action—without it, nothing would be accomplished. But excessive or misdirected rajas creates the endless cycle of craving and aversion that Krishna identifies as the enemy.

Rajas in Modern Life

Our contemporary culture is heavily rajasic: constant stimulation, endless content, perpetual pursuit of more. The advertising industry deliberately amplifies desire. Social media triggers comparison and inadequacy. News cycles provoke outrage. We swim in a sea of rajas.

Understanding this isn't about rejecting modern life but about cultivating awareness of what feeds rajas and what cultivates sattva. Diet, media consumption, relationships, environments—all influence our guna balance.

The All-Devouring Nature

Krishna uses the striking term "mahāśana"—great devourer. This metaphor reveals essential truths about desire's nature.

Desire Consumes What It Promises

The objects we desire promise satisfaction but deliver only more desire. The person who craves wealth, upon obtaining it, craves more. The person who seeks fame finds it hollow and seeks more. Like a fire that grows larger when fed, desire increases with indulgence, not decreases.

The Fire Analogy

Commentators often compare desire to fire fed with ghee:

"As fire is never satisfied by fuel, nor the ocean by rivers, nor death by all living beings, so desire is never satisfied by enjoyment."

This is not a pessimistic teaching but a realistic one. Understanding desire's insatiable nature frees us from the illusion that "just this one thing" will satisfy us. Peace comes not from fulfilling desires but from understanding their nature and finding happiness independent of them.

What Desire Devours

  • Peace: The desiring mind is restless, never at ease
  • Time: Endless pursuit consumes life's precious moments
  • Relationships: When people become means to our ends
  • Health: Stress from craving damages body and mind
  • Wisdom: Desire clouds discrimination
  • Freedom: We become slaves to what we crave

Know This as the Enemy

Krishna's imperative "viddhi" (know!) combined with "vairiṇam" (enemy) demands we take this seriously. This isn't casual information but urgent intelligence for the spiritual battle.

Why "Enemy"?

An enemy is something that harms us, opposes our well-being, and must be resisted. Desire and anger qualify because they:

  • Oppose our liberation and peace
  • Lead us to actions we regret
  • Cloud our wisdom and discrimination
  • Create suffering for ourselves and others
  • Bind us to the cycle of reactivity

The Internal Enemy

What makes this enemy particularly dangerous is that it's internal. We can flee external enemies, but we carry this one everywhere. It disguises itself as our own voice: "I want," "I need," "I deserve." We mistake it for ourselves rather than recognizing it as an impersonal force operating through us.

🎯 The Real Battle

The battlefield of Kurukshetra is traditionally understood as both literal and symbolic—the field where dharma and adharma contend. That field is also within us, where wisdom battles desire. The Gita is ultimately a manual for this internal warfare.

Overcoming the Enemy

Identifying the enemy is the first step; Krishna continues in subsequent verses to explain how to overcome it. Key strategies include:

🧘 Strategy 1: Understand Its Locations

In verse 3.40, Krishna identifies where desire hides: the senses, mind, and intellect. By observing these, we can catch desire early, before it gains momentum.

🧘 Strategy 2: Control the Senses

The senses are the gateway for desire. Sense control (indriya-nigraha) doesn't mean suppression but wise regulation—not feeding every impulse, choosing what to expose ourselves to.

🧘 Strategy 3: Cultivate Sattva

Since desire is born of rajas, cultivating sattva naturally reduces it. Sattvic diet, company, media, and practices create an environment less hospitable to desire's arising.

🧘 Strategy 4: Strengthen Buddhi

The intellect (buddhi), when aligned with wisdom, can override desire. Developing discrimination through study, reflection, and practice strengthens our capacity to say no to harmful desires.

🧘 Strategy 5: Practice Karma Yoga

Acting without attachment to results (karma yoga) starves desire of its food. When we stop acting for personal gain, desire loses its grip.

🧘 Strategy 6: Meditation

Regular meditation creates the spaciousness to observe desire without acting on it. We see the arising of wanting, watch it pass, and discover we don't have to obey every impulse.

Frequently Asked Questions

What does Bhagavad Gita 3.37 teach?

Verse 3.37 reveals that desire (kama) and anger (krodha), born from the quality of passion (rajas), are the great enemies of the soul. These are all-devouring and all-sinful, causing beings to act against their own wisdom and well-being.

How are desire and anger connected?

According to the Gita, anger is frustrated desire. When we want something and it's blocked or denied, desire transforms into anger. They are two faces of the same energy—rajas (passion). Desire (kama) is the root, and anger (krodha) is its offspring when desire is thwarted.

What is rajas guna and why does it cause problems?

Rajas is one of three gunas (qualities) in Vedic philosophy. It represents passion, activity, and restlessness. While necessary for action, excessive rajas creates attachment, craving, and agitation. It drives the endless pursuit of pleasure and the reactive anger when pleasure is denied.

How can I overcome desire and anger according to the Gita?

The Gita recommends: understanding their nature and origin, cultivating sattva through pure practices, regular meditation, practicing karma yoga (action without attachment), and developing buddhi (discriminative wisdom) to override reactive patterns.

Why does Krishna call desire and anger "all-devouring"?

Krishna uses "mahāśana" (great devourer) because desire is never satisfied—fulfilling one desire creates more. Like fire fed with fuel, satisfying desire increases it. Similarly, anger consumes peace, relationships, health, and spiritual progress without ever being satiated.
