1-2. Chapter one introduced the setting in which Arjun's grief and lamentation arose, creating a reason for Shree Krishna to give spiritual instructions. In chapter two, the Lord first explained knowledge of the immortal self. He then reminded Arjun of his duty as a warrior, and said that performing it would result in glory and the celestial abodes. After prodding Arjun to do his occupational work as a Kshatriya, Shree Krishna then revealed a superior principle—the science of karm yog—and asked Arjun to detach himself from the fruits of his works. In this way, bondage-creating karmas would be transformed into bondage-breaking karmas. He termed the science of working without desire for rewards as buddhi yog, or Yog of the intellect. By this, he meant that the mind should be detached from worldly temptations by controlling it with a resolute intellect; and the intellect should be made unwavering through the cultivation of spiritual knowledge. He did not suggest that actions should be given up, but rather that attachment to the fruits of actions should be given up.
Arjun misunderstood Shree Krishna's intention, thinking that if knowledge is superior to action, then why should he perform the ghastly duty of waging this war? Hence, he says, "By making contradictory statements, you are bewildering my intellect. I know you are merciful and your desire is not to baffle me, so please dispel my doubt."
3. In verse , Shree Krishna explained the two paths leading to spiritual perfection. The first is the acquisition of knowledge through the analytical study of the nature of the soul and its distinction from the body. Shree Krishna refers to this as sānkhya yog. People with a philosophic bend of mind are inclined toward this path of knowing the self through intellectual analysis. The second is the process of working in the spirit of devotion to God, or karm yog. Shree Krishna also calls this buddhi yog¸ as explained in the previous verse. Working in this manner purifies the mind, and knowledge naturally awakens in the purified mind, thus leading to enlightenment.
Amongst people interested in the spiritual path, there are those who are inclined toward contemplation and then there are those inclined to action. Hence, both these paths have existed ever since the soul's aspiration for God-realization has existed. Shree Krishna touches upon both of them since his message is meant for people of all temperaments and inclinations.
4. The first line of this verse refers to the karm yogi (follower of the discipline of work), and the second line refers to the sānkhya yogi (follower of the discipline of knowledge).
In the first line, Shree Krishna says that mere abstinence from work does not result in a state of freedom from karmic reactions. The mind continues to engage in fruitive thoughts, and since mental work is also a form of karma, it binds one in karmic reactions, just as physical work does. A true karm yogi must learn to work without any attachment to the fruits of actions. This requires cultivation of knowledge in the intellect. Hence, philosophic knowledge is also necessary for success in karm yog.
In the second line, Shree Krishna declares that the sānkhya yogi cannot attain the state of knowledge merely by renouncing the world and becoming a monk. One may give up the physical objects of the senses, but true knowledge cannot awaken as long as the mind remains impure. The mind has a tendency to repeat its previous thoughts. Such repetition creates a channel within the mind, and new thoughts flow irresistibly in the same direction. Out of previous habit, the materially contaminated mind keeps running in the direction of anxiety, stress, fear, hatred, envy, attachment, and the whole gamut of material emotions. Thus, realized knowledge will not appear in an impure heart by mere physical renunciation. It must be accompanied by congruent action that purifies the mind and intellect. Therefore, action is also necessary for success in sānkhya yog.
It is said that devotion without philosophy is sentimentality, and philosophy without devotion is intellectual speculation. Action and knowledge are necessary in both karm yog and sānkhya yog. It is only their proportion that varies, creating the difference between the two paths.
5. Some people think that action refers only to professional work, and not to daily activities such as eating, drinking, sleeping, waking and thinking. So when they renounce their profession, they think they are not performing actions. But Shree Krishna considers all activities performed with the body, mind, and tongue as actions. Hence, he tells Arjun that complete inactivity is impossible even for a moment. If we simply sit down, it is an activity; if we lie down, that is also an activity; if we fall asleep, the mind is still engaged in dreaming; even in deep sleep, the heart and other bodily organs are functioning. Thus Shree Krishna declares that for human beings inactivity is an impossible state to reach, since the body-mind-intellect mechanism is compelled by its own make-up of the three guṇas (sattva, rajas, and tamas) to perform work in the world. The Śhrīmad Bhāgavatam contains a similar verse:
"Nobody can remain inactive for even a moment. Everyone is forced to act by their modes of nature."
6. Attracted by the lure of an ascetic life, people often renounce their work, only to discover later that their renunciation is not accompanied by an equal amount of mental and intellectual withdrawal from the sensual fields. This creates a situation of hypocrisy where one displays an external show of religiosity while internally living a life of ignoble sentiments and base motives. Hence, it is better to face the struggles of the world as a karm yogi, than to lead the life of a false ascetic. Running away from the problems of life by prematurely taking sanyās is not the way forward in the journey of the evolution of the soul. Saint Kabir stated sarcastically:
"O Ascetic Yogi, you have donned the ochre robes, but you have ignored dyeing your mind with the color of renunciation. You have grown long locks of hair and smeared ash on your body (as a sign of detachment). But without the internal devotion, the external beard you have sprouted only makes you resemble a goat." Shree Krishna states in this verse that people who externally renounce the objects of the senses while continuing to dwell upon them in the mind are hypocrites, and they delude themselves.
The Puranas relate the story of two brothers, Tavrit and Suvrit, to illustrate this point. The brothers were walking from their house to hear the Śhrīmad Bhāgavatam discourse at the temple. On the way, it began raining heavily, so they ran into the nearest building for shelter. To their dismay, they found themselves in a brothel, where women of disrepute were dancing to entertain their guests. Tavrit, the elder brother, was appalled and walked out into the rain, to continue to the temple. The younger brother, Suvrit, felt no harm in sitting there for a while to escape getting wet in the rain.
Tavrit reached the temple and sat for the discourse, but in his mind he became remorseful, "O how boring this is! I made a dreadful mistake; I should have remained at the brothel. My brother must be enjoying himself greatly in revelry there." Suvrit, on the other hand, started thinking, "Why did I remain in this house of sin? My brother is so holy; he is bathing his intellect in the knowledge of the Bhāgavatam. I too should have braved the rain and reached there. After all, I am not made of salt that I would have melted in a little bit of rain."
When the rain stopped, both started out in the direction of the other. The moment they met, lightning struck them and they both died on the spot. The Yamdoots (servants of the god of Death) came to take Tavrit to hell. Tavrit complained, "I think you have made a mistake. I am Tavrit. It was my brother who was sitting at the brothel a little while ago. You should be taking him to hell." The Yamdoots replied, "We have made no mistake. He was sitting there to avoid the rain, but in his mind he was longing to be at the Bhāgavatam discourse. On the other hand, while you were sitting and hearing the discourse, your mind was yearning to be at the brothel." Tavrit was doing exactly what Shree Krishna declares in this verse; he had externally renounced the objects of the senses, but was dwelling upon them in the mind. This was the improper kind of renunciation. The next verse states the proper kind of renunciation.
