Bhagavad Gita 18.20–29: Deep Dive

The Three Gunas – How Sattva, Rajas and Tamas Shape Our Knowledge, Actions and Character


Add to Favorites

Central theme: In these verses, Krishna explains that the three gunas (Sattva, Rajas and Tamas) influence everything about human behaviour – how we see the world, how we make decisions, how we act, our motivations and even our inner state.

This is a particularly important section because Krishna moves beyond simply telling Arjuna what is right or wrong. He teaches him to understand the quality of consciousness behind everything he does.

Let's explore each verse.

1. Verse 18.20 – Sattvic Knowledge (Wisdom that sees unity)

Main teaching: True knowledge sees the one Divine reality present in all living beings, despite their different forms.


Add to Favorites

Krishna describes knowledge through which a person sees:

  • One eternal, imperishable reality in all beings.

  • The same spiritual essence in different bodies.

  • Unity despite external differences.

  • The interconnectedness of all creation.

Deep meaning

Most people identify others through external differences:

  • Rich or poor.

  • Educated or uneducated.

  • Successful or unsuccessful.

  • Attractive or unattractive.

  • Friend or enemy.

But Sattvic knowledge looks beyond these differences.

It recognises that the same Atman (Self) exists in everyone.

For example, imagine meeting someone who has made serious mistakes in life.

An ordinary reaction might be to judge the person entirely by their behaviour.

Sattvic understanding distinguishes between the person's actions and their deeper spiritual nature.

It doesn't mean accepting harmful behaviour. It means not losing sight of the underlying unity of life.

Practical lesson: See differences in people's circumstances, but don't forget the deeper equality of their spiritual essence.

Reflection: Do I see people as they truly are, or do I judge them according to their status, appearance and behaviour?

2. Verse 18.21 – Rajasic Knowledge (Seeing division)

Main teaching: Rajasic knowledge sees multiplicity, separation and differences as the dominant reality.

Krishna explains that this knowledge sees different beings as separate and distinct, without recognising the underlying unity.

Deep meaning

This is how the ego often interprets the world.

The mind constantly compares:

  • My success versus your success.

  • My family versus your family.

  • My achievements versus your achievements.

  • My beliefs versus your beliefs.

The world becomes a competition.

The individual starts thinking:

  • I must be better than others.

  • I must receive more recognition.

  • I must protect my position.

  • Other people's success threatens mine.

The problem is not recognising differences. Differences are real at the practical level.

The problem is becoming so absorbed in differences that we lose sight of our shared humanity.

Example

Two colleagues receive promotions.

  • A Sattvic person may appreciate both achievements.

  • A Rajasic person may become jealous, competitive or preoccupied with comparison.

Practical lesson: Competition can motivate us, but excessive comparison creates insecurity and separation.

Reflection: Can I celebrate someone else's success without feeling that it diminishes my own?

3. Verse 18.22 – Tamasic Knowledge (Ignorance and narrow understanding)

Main teaching: Tamasic knowledge is limited, irrational and attached to one small aspect of reality as though it were the whole truth.

Krishna describes knowledge that:

  • Clings to one particular thing.

  • Does not understand the wider reality.

  • Lacks proper reasoning.

  • Is narrow and disconnected from truth.

Deep meaning

This is perhaps one of the most dangerous forms of ignorance.

A person becomes convinced that their limited understanding is the complete truth.

For example:

Someone hears one side of an argument and immediately decides who is right and wrong.

They refuse to investigate further.

They don't question their assumptions.

They don't consider alternative explanations.

This is Tamasic thinking.

It can also appear as blind superstition, irrational attachment and refusing to learn.

Practical lesson: Don't confuse strong conviction with genuine understanding.

Wisdom requires openness, reflection and discernment.

Reflection: Am I willing to question my beliefs when new evidence or deeper understanding becomes available?

4. Verse 18.23 – Sattvic Action (Selfless and balanced action)

Main teaching: The highest quality of action is performed without attachment, personal craving or hatred.

Krishna describes Sattvic action as action that is:

  • Performed as a duty.

  • Free from excessive attachment.

  • Without selfish desire for results.

  • Free from attraction and aversion.

Deep meaning

This verse connects directly with one of the most important teachings of the Bhagavad Gita:

Perform your duty, but don't become attached to the fruits of your actions.

For example:

A teacher teaches because educating others is their responsibility.

A parent cares for their children because it is an expression of love and responsibility.

A person helps someone in need without expecting praise or repayment.

The action is important in itself.

This does not mean we should stop having goals or ambitions.

It means our inner peace should not depend entirely on whether we achieve them.

Important distinction:

Sattvic action is not passive action.

It can involve enormous effort, courage and discipline.

The difference lies in the consciousness behind the effort.

Practical lesson: Give your best to the work without allowing the outcome to control your inner peace.

5. Verse 18.24 – Rajasic Action (Action driven by desire and ego)

Main teaching: Rajasic action is performed with attachment, personal ambition and considerable effort driven by desire.

Krishna identifies three characteristics:

  1. Desire for personal gain.

  2. Ego and a sense of self-importance.

  3. Action driven by craving and attachment.

Deep meaning

The person is active, ambitious and energetic.

However, their actions are strongly driven by personal rewards.

For example:

A person works extremely hard, but their primary motivation is:

  • Recognition.

  • Wealth.

  • Social status.

  • Power.

  • Praise.

  • Being considered superior to others.

There is nothing inherently wrong with wealth, achievement or recognition.

The issue is becoming psychologically dependent on them.

When success comes, the person feels temporarily satisfied.

When failure comes, they become frustrated, angry or depressed.

Their happiness becomes dependent on external results.

Practical lesson: Ambition is useful, but ambition controlled by ego becomes a source of bondage.

Reflection: Am I doing this because it is meaningful and right, or primarily because I want recognition?

6. Verse 18.25 – Tamasic Action (Action without understanding)

Main teaching: Tamasic action is undertaken through ignorance, without considering consequences, one's capabilities or the harm caused.

Krishna highlights four features:

  • Failure to consider consequences.

  • Failure to consider potential loss.

  • Failure to consider harm to others.

  • Acting without properly understanding one's capacity.

Deep meaning

This is action without awareness.

Examples include:

  • Making impulsive decisions without thinking.

  • Acting out of anger and damaging relationships.

  • Taking unnecessary risks.

  • Avoiding responsibility.

  • Continuing harmful behaviour despite knowing its consequences.

  • Starting something without considering whether one has the ability or resources to complete it.

The person acts, but there is little discernment.

Practical lesson: Before acting, pause and consider the consequences for yourself and others.

Not every action is necessarily a good action simply because it is energetic or decisive.

7. Verse 18.26 – Sattvic Doer (The person who acts with wisdom)

Main teaching: A Sattvic doer performs their responsibilities with balance, determination and freedom from ego.

Krishna describes such a person as:

  • Free from attachment.

  • Free from egoistic identification.

  • Steady and enthusiastic.

  • Unaffected by success and failure.

Deep meaning

This verse is particularly powerful because Krishna now moves from the quality of action to the quality of the person performing it.

A Sattvic person doesn't constantly think:

"Look what I have achieved."

They understand that many factors contribute to success.

They work sincerely but don't become arrogant when things go well.

Equally, they don't collapse emotionally when things go wrong.

They maintain inner balance.

Example

Two people run a business.

Person A becomes arrogant when profits increase and angry when profits decrease.

Person B works diligently, learns from mistakes, treats people fairly and remains balanced through changing circumstances.

Person B demonstrates the Sattvic qualities Krishna describes.

Practical lesson: Your character is revealed not only by what you achieve, but by how you respond to success and failure.

8. Verse 18.27 – Rajasic Doer (The person controlled by results)

Main teaching: The Rajasic doer is strongly attached to the results of action and is influenced by desire, greed, excitement, sorrow and fluctuating emotions.

Krishna describes characteristics such as:

  • Attachment to results.

  • Desire for rewards.

  • Greed.

  • Impurity of intention.

  • Excessive happiness when successful.

  • Distress when unsuccessful.

Deep meaning

This person allows circumstances to determine their emotional state.

When things go well, they feel powerful.

When things go badly, they feel defeated.

Their identity becomes attached to achievement.

Consider someone who receives praise at work.

They feel wonderful.

But when another person receives more praise, they feel threatened.

Why?

Because their sense of self-worth depends on external validation.

This is the psychological bondage of Rajas.

Practical lesson: Notice when your emotional wellbeing becomes dependent on praise, possessions, achievements or other people's approval.

9. Verse 18.28 – Tamasic Doer (The person controlled by ignorance)

Main teaching: The Tamasic doer is characterised by carelessness, indiscipline, stubbornness, dishonesty and lack of responsibility.

Krishna identifies several qualities:

  • Lack of self-control.

  • Vulgar or inappropriate conduct.

  • Stubbornness.

  • Deception.

  • Malice.

  • Laziness.

  • Despondency.

  • Procrastination.

Deep meaning

This verse describes a person who repeatedly avoids personal responsibility.

They may:

  • Blame others for their difficulties.

  • Refuse to learn from mistakes.

  • Postpone necessary work.

  • Resist constructive advice.

  • Act dishonestly to avoid consequences.

  • Remain trapped in negative habits.

An especially important quality here is pramāda – carelessness, heedlessness or lack of awareness.

A person may know what needs to be done but repeatedly fail to act responsibly.

Practical lesson: Spiritual growth requires awareness, discipline and the willingness to take responsibility for one's choices.

10. Verse 18.29 – The Three Gunas and the Power of Discernment


Add to Favorites

Main teaching: Krishna introduces the classification of Buddhi (intellect/discriminative understanding) and Dhriti (steadfastness or inner determination) according to the three gunas.

This verse is a transition into the next section.

It is particularly important because it introduces two powers that determine the direction of human life.

A. Buddhi – The power of discernment

Buddhi helps us distinguish:

  • Right from wrong.

  • Duty from non-duty.

  • What should be done and what should be avoided.

  • Fear and fearlessness.

  • Bondage and liberation.

It is the faculty that helps us make wise decisions.

B. Dhriti – The power of determination

Dhriti enables us to:

  • Remain committed to our responsibilities.

  • Maintain discipline.

  • Control impulses.

  • Continue despite difficulties.

  • Stay focused on meaningful goals.

Deep meaning

A person may know what is right but lack the determination to follow it.

For example:

Someone knows that anger damages relationships.

Their Buddhi recognises the problem.

But when anger arises, they cannot control their reaction.

Their Dhriti is not sufficiently developed.

Similarly, someone may have tremendous determination but use it to pursue selfish or harmful goals.

Therefore, wisdom and determination must work together.

Practical lesson: It is not enough to know what is right. We must develop the strength to consistently live according to that understanding.

The overall comparison: Verses 20–29

This is the central framework Krishna wants Arjuna to understand.

AreaSattvaRajasTamas
KnowledgeSees unitySees separationSees narrowly
ActionDuty without attachmentDesire and egoIgnorance and carelessness
DoerBalanced and humbleGreedy and attachedLazy and irresponsible
IntellectClear discernmentDistorted by desireClouded by ignorance
DeterminationSteady in wisdomDriven by ambitionDriven by inertia

Note: Verse 18.29 introduces the classification of intellect and determination; their detailed descriptions follow in verses 18.30–35.

7 profound spiritual insights from Bhagavad Gita 18.20–29

1. The quality of your knowledge determines how you see the world.

If you see only differences, you experience separation. If you recognise the underlying unity, compassion naturally develops.

2. The same action can have different spiritual qualities.

Helping someone could be Sattvic, Rajasic or Tamasic depending on the intention, understanding and awareness behind it.

3. Ego is a major source of bondage.

The belief that everything happens because of "me" and "my achievements" creates attachment.

4. Success and failure are tests of inner maturity.

Sattvic consciousness remains balanced through both.

5. Activity does not automatically mean progress.

Rajas creates constant activity, while Tamas creates inertia. Sattva brings clarity about what deserves action.

6. Spiritual development requires self-observation.

Instead of constantly judging others, observe your own knowledge, intentions, actions and reactions.

7. Wisdom must be supported by discipline.

Knowing the right path is not enough. We must have the determination to walk it.

Applying these verses to everyday life

Here are five practical situations through which you can examine the three gunas.

SituationSattvic responseRajasic responseTamasic response
Someone criticises youReflect calmlyBecome defensiveReact carelessly or maliciously
Someone succeedsFeel genuinely happyBecome jealousDismiss or undermine them
Work becomes difficultPersist with balanceBecome frustrated over resultsGive up or procrastinate
You help someoneHelp without expectationExpect appreciationHelp carelessly or with harmful motives
You make a mistakeAccept and learnBlame circumstancesDeny responsibility

A daily self-reflection exercise

At the end of each day, ask yourself:

  1. Did I see the deeper humanity in people, or judge them by appearances?

  2. Were my actions driven by duty or by personal recognition?

  3. Did I remain balanced when things didn't go my way?

  4. Did I act with awareness or out of impulse?

  5. Did I follow through on what I knew was right?

These questions turn the Gita from philosophical knowledge into a practical method of self-transformation.

The deepest message of this passage

Krishna is teaching Arjuna that spiritual evolution is not simply about changing external behaviour.

It is about transforming the consciousness from which behaviour emerges.

  • Tamas: I act without awareness.

  • Rajas: I act because I want something.

  • Sattva: I act with clarity, responsibility and without attachment.

There is also an important qualification: Sattva is the highest of the three gunas, but it is not the ultimate destination. Even attachment to goodness and knowledge can bind a person. The Gita ultimately teaches transcendence of all three gunas (developed in Chapter 14).

A thought to carry with you

"Don't just ask yourself: What am I doing?

Ask yourself: From what state of consciousness am I doing it?"

This captures the practical heart of Bhagavad Gita 18.20–29.

The next particularly valuable study is Bhagavad Gita 18.30–35, where Krishna explains Sattvic, Rajasic and Tamasic intellect and determination in greater detail. These verses give us a deeper understanding of how to develop discernment, self-control and spiritual discipline.
