Chapter 4 opens with the lineage of this yoga: Krishna taught it to Vivasvan, who taught Manu (4.1). A few verses later comes a widely quoted passage, Krishna's promise that whenever dharma declines, he appears to restore it (4.7–8). Most of the chapter, though, is about action: how to act without being bound, the many kinds of sacrifice, knowledge as the fire that burns karma (4.37), and how to learn from a teacher (4.34).
This is also the first chapter where Krishna speaks openly about his own nature. In 4.9 he says that whoever understands his birth and action is not born again.
Verses 4.7–4.8 · The Divine Promise
The Divine Promise: Goodness Will Be Protected
These two verses are among the best known in the chapter, and they have been quoted in support of all kinds of causes. Read closely, they promise that dharma has a protector who comes back when it is in decline.
Bhagavad Gita 4.7Speaker: Krishna
यदा यदा हि धर्मस्य ग्लानिर्भवति भारत ।
अभ्युत्थानमधर्मस्य तदाऽऽत्मानं सृजाम्यहम् ॥
अभ्युत्थानमधर्मस्य तदाऽऽत्मानं सृजाम्यहम् ॥

abhyutthānamadharmasya tadā''tmānaṃ sṛjāmyaham ||
“Whenever dharma declines and adharma rises, Krishna manifests himself.”

dharmasaṃsthāpanārthāya saṃbhavāmi yuge yuge ||
Meaning
To protect the righteous, to destroy the wicked, and to re-establish dharma, I am born age after age.
The deeper dimension
This verse gives the three reasons Krishna takes birth: to protect the good, to destroy wrongdoers, and to re-establish dharma. In the Gita, protecting the good includes ending the harm done to them.
“He is born age after age to protect the good, destroy the wicked and restore dharma.”
Read full verse + audio →Krishna says this plainly. He doesn't treat Arjuna's moment as special; he describes how things go: when dharma declines, he comes back to set it right (4.7–8).
Verses 4.9–4.14 · The Nature of Divine Action
What Does It Mean to Know the Divine?
In verses 9 to 14 Krishna moves from history to the listener: what happens to someone who understands him.
Bhagavad Gita 4.9Speaker: Krishna
जन्म कर्म च मे दिव्यमेवं यो वेत्ति तत्त्वतः ।
त्यक्त्वा देहं पुनर्जन्म नैति मामेति सोऽर्जुन ॥
त्यक्त्वा देहं पुनर्जन्म नैति मामेति सोऽर्जुन ॥
janma karma ca me divyamevaṃ yo vetti tattvataḥ |
tyaktvā dehaṃ punarjanma naiti māmeti so'rjuna ||
tyaktvā dehaṃ punarjanma naiti māmeti so'rjuna ||
Meaning
One who truly knows the divine nature of my birth and activities does not take birth again after leaving this body but comes to me, O Arjuna.
The core teaching
The verse says that knowing (vetti tattvataḥ) Krishna's birth and action as divine is enough to end rebirth. The knowing it describes is a direct understanding of who Krishna is.
“One who knows his divine birth and action escapes rebirth and comes to him.”
Read full verse + audio →A structural note: Verses 7–8 say why Krishna takes birth. Verse 9 says that understanding this is itself freeing, and 4.10 adds that many have already reached his state this way.
Verse 4.33 · Knowledge as Offering
Knowledge as the Greatest Yajna
Verses 4.25–32 list many kinds of yajna: offerings to the gods, restraint of the senses, gifts of wealth, breath control, study. Verse 33 ranks them.
Bhagavad Gita 4.33Speaker: Krishna
श्रेयान्द्रव्यमयाद्यज्ञाज्ज्ञानयज्ञः परन्तप ।
सर्वं कर्माखिलं पार्थ ज्ञाने परिसमाप्यते ॥
सर्वं कर्माखिलं पार्थ ज्ञाने परिसमाप्यते ॥
śreyāndravyamayādyajñājjñānayajñaḥ parantapa |
sarvaṃ karmākhilaṃ pārtha jñāne parisamāpyate ||
sarvaṃ karmākhilaṃ pārtha jñāne parisamāpyate ||
Meaning
O destroyer of enemies, the sacrifice of knowledge is superior to the sacrifice of material things. All action in its entirety finds its culmination in wisdom, O Arjuna.
What it adds
All the offerings listed before this verse are actions. Krishna says every action reaches its end (parisamāpyate) in jnana, knowledge, so knowledge ranks above the rest.
“The sacrifice of knowledge is greater than that of things; all action ends in knowledge.”

Verse 4.34 · How to Approach a Teacher
How to Learn From a Teacher
If knowledge is the greatest offering, how does one get it? Verse 4.34 answers with three things the student does.
Bhagavad Gita 4.34Speaker: Krishna
तद्विद्धि प्रणिपातेन परिप्रश्नेन सेवया ।
उपदेक्ष्यन्ति ते ज्ञानं ज्ञानिनस्तत्त्वदर्शिनः ॥
उपदेक्ष्यन्ति ते ज्ञानं ज्ञानिनस्तत्त्वदर्शिनः ॥
tadviddhi praṇipātena paripraśnena sevayā |
upadekṣyanti te jñānaṃ jñāninastattvadarśinaḥ ||
upadekṣyanti te jñānaṃ jñāninastattvadarśinaḥ ||
Meaning
Know that wisdom by prostrating yourself (humility), by sincere questioning, and by service. The wise seers of truth will impart knowledge to you.
The framework
Three things: praṇipāta (bowing, humility), paripraśna (asking questions to understand, as opposed to scoring points), and sevā (service). The teachers named here are those who have seen the truth (tattva-darśinaḥ).
“Learn it by bowing, questioning and serving; those who have seen the truth will teach you.”
Read full verse + audio →The verse is often cited as a model for the guru-disciple relationship. A teacher, on this reading, looks for a student who sets ego aside, asks to understand rather than to argue, and contributes to the place where they learn.
Verses 4.37–4.38 · The Fire of Wisdom
Knowledge Is a Fire That Burns Karma
In verses 37 and 38 Krishna describes knowledge as a fire that burns.
Bhagavad Gita 4.37Speaker: Krishna
यथैधांसि समिद्धोऽग्निर्भस्मसात्कुरुतेऽर्जुन ।
ज्ञानाग्निः सर्वकर्माणि भस्मसात्कुरुते तथा ॥
ज्ञानाग्निः सर्वकर्माणि भस्मसात्कुरुते तथा ॥
yathaidhāṃsi samiddho'gnirbhasmasātkurute'rjuna |
jñānāgniḥ sarvakarmāṇi bhasmasātkurute tathā ||
jñānāgniḥ sarvakarmāṇi bhasmasātkurute tathā ||
Meaning
As a blazing fire reduces wood to ashes, O Arjuna, so the fire of knowledge reduces all karma to ashes.
The claim
The verse says all karma (sarva-karmāṇi) is burnt to ash, which goes further than reducing it. Most commentators read this as the stored karma from past actions losing its hold once the self is known.
“As fire turns wood to ash, the fire of knowledge turns all karma to ash.”
Read full verse + audio →Bhagavad Gita 4.38Speaker: Krishna
न हि ज्ञानेन सदृशं पवित्रमिह विद्यते ।
तत्स्वयं योगसंसिद्धः कालेनात्मनि विन्दति ॥
तत्स्वयं योगसंसिद्धः कालेनात्मनि विन्दति ॥
na hi jñānena sadṛśaṃ pavitramiha vidyate |
tatsvayaṃ yogasaṃsiddhaḥ kālenātmani vindati ||
tatsvayaṃ yogasaṃsiddhaḥ kālenātmani vindati ||
Meaning
Nothing in this world is as purifying as wisdom. One who is perfected in yoga finds this wisdom within the self, in the course of time.
The patience required
The word kālena, "in the course of time", matters. Knowledge comes to the person practising yoga over time; the verse doesn't promise it overnight.
“Nothing here purifies like knowledge; one perfected in yoga finds it within in time.”

Arise: From Understanding to Action
Chapter 4 ends with an instruction to act:
Bhagavad Gita 4.42Speaker: Krishna
तस्मादज्ञानसंभूतं हृत्स्थं ज्ञानासिनाऽऽत्मनः ।
छित्त्वैनं संशयं योगमातिष्ठोत्तिष्ठ भारत ॥
छित्त्वैनं संशयं योगमातिष्ठोत्तिष्ठ भारत ॥
tasmādajñānasaṃbhūtaṃ hṛtsthaṃ jñānāsinā''tmanaḥ |
chittvainaṃ saṃśayaṃ yogamātiṣṭhottiṣṭha bhārata ||
chittvainaṃ saṃśayaṃ yogamātiṣṭhottiṣṭha bhārata ||
Meaning
Therefore, with the sword of knowledge, cut asunder the doubt born of ignorance that has lodged in your heart. Take refuge in yoga, arise, O Arjuna.
The pivot
"Arise", uttiṣṭha, is Krishna's last instruction in Chapter 4. It repeats his first one in 2.3. After the teaching on knowledge, he tells Arjuna to stand up and act.
“Cut the doubt in your heart with the sword of knowledge, hold to yoga, and stand up.”
Read full verse + audio →In the last verse (4.42) Krishna tells Arjuna to cut through his doubt with knowledge, hold to yoga, and stand up: uttiṣṭha.

Frequently Asked Questions
What is Bhagavad Gita Chapter 4 about?
Chapter 4, called Jnana Karma Sanyasa Yoga, covers three major themes: Krishna's promise to return in every age to restore dharma (4.7–4.8), action without attachment, and knowledge, described as a fire that burns away all karma. It also says how to approach a teacher: with humility, questions and service (4.34).
What is the meaning of "yada yada hi dharmasya"?
This is the opening of verse 4.7. The full verse: "Whenever there is a decline in dharma (righteousness) and an increase in adharma (unrighteousness), O Arjuna, I manifest myself." It is widely quoted and usually paired with 4.8: "To protect the righteous, destroy the wicked, and re-establish dharma, I am born age after age." Together they say that Krishna returns, age after age (yuge yuge), whenever dharma needs restoring.
What does the Bhagavad Gita say about how to learn?
Verse 4.34 says to learn from those who have seen the truth by bowing to them, asking questions, and serving them. Those teachers, Krishna says, will then pass on the knowledge.
What is "jnana yajna" in the Gita?
Jnana yajna means the sacrifice (offering) of knowledge or wisdom. In verse 4.33, Krishna says it is superior to material sacrifices because all actions find their completion in wisdom. So the best offering a person can make is understanding.
How many verses are in Chapter 4 of the Bhagavad Gita?
Chapter 4 has 42 verses. It is also known as Jnana Karma Sanyasa Yoga, the Yoga of Renunciation of Action through Knowledge.
