In this chapter, Sri Krishna speaks about the timeless origin of Brahmavidya (the supreme Knowledge) and the lineage of instructors (Guru-parampara), who embodied and imparted the eternal message.
Krishna then explains what action and inaction truly are. The Self is bereft of all action, no matter how active one otherwise appears to be. Equally so, even when the body is still, the mind and the other functions will be there – like digestion, circulation of blood and flow of breath which are ceaseless processes. By the knowledge and understanding of the non-acting Self, the fallacy of inaction disappears and one becomes an all-performer.
One who performs all activities being free of delusional clinging, expectations, and desires is a non-doer, even though engaged in multifarious activities. Activities do not bind a person who has renounced ego.
Activity is indispensable in Nature. However, Krishna says that in the active life, the spirit of renunciation must be ingrained. No activity, performed as a yoga, will bring any sin and bondage. Sri Krishna instructs Arjuna to get rid of all doubts by reflecting upon the Truth of the Self within and to act resolutely.
In this chapter, Sri Krishna integrates activity with spiritual knowledge. Karma, instead of posing any contradiction or hindrance, verily becomes a harmonious complement to spiritual wisdom, and spiritual wisdom, in turn, enriches Karma.
Lord Krishna said: I first imparted this imperishable spiritual science (yoga) to Vivasvan. Vivasvan told Manu about it; and Manu spoke to Ikshvaku.
This yoga (spiritual science), handed down thus through the Guru-śishya lineage, was possessed well by the Knower kings (Rajarshis). But by passage of inexorable time, it has got lost, O scorcher of enemies!
That most ancient spiritual science itself has been divulged to you by me. You are devoted to me; you are also my friend; hence, I felt like revealing to you this most beneficial secret.
Arjuna said: Your birth was much later, and Vivasvan’s earlier. How can I then understand that you instructed this first?
Lord Krishna said: Many births have been for me, so too for you, O Arjuna. All those I know well, but, O Scorcher of foes, alas, you do not.
Although I am unborn, of indestructible nature, the Lord of all beings, by dint of my inscrutable power, wielding my own Nature, I get born again and again.
Whenever, O Bharata (Arjuna), righteousness declines and unrighteousness grows, I manifest specially. For protection of the benevolent and eradication of the wicked, to establish righteousness, I manifest time and again.
Whoever knows in essence My birth and activity as divine in this manner, abandoning the body attains Me and does not have re-birth, O Arjuna.
Transcending passion, fear and anger, reflecting constantly upon Me, taking refuge in Me, many have become like Me getting purified by knowledge-austerity.
As men seek Me, O Partha, so do I grace them with My favour. All humans are following My path only in every way.
People worship various deities, aspiring the rewards of rituals. In the human world, fruition of such piecemeal worship is easily had.
The arrangement called four-fold varṇas, based upon the inner qualities and outer activities of people, is instituted by Me. Though the Creator of such a categorization, know Me as a Non-doer, the Imperishable.
Actions do not taint me. For, I have no yearning for the result of any action. Whoever understands me in this manner, will not be bound by the actions he does.
Understanding matters thus in full light, seekers in the past had performed their activities well. Therefore, you too do yours, as did your predecessors.
Even the wise ones are confused about what constitutes right action, and what does not. Therefore, I shall tell you what is verily an action, by knowing which you will be free from the inauspicious effects thereof.
The nature of true action is to be known; so too of forbidden action. One also has to know what constitutes inaction. For, the course and consequences of action are abstruse.
Whoever sees inaction or actionless-ness in action, and activity in inaction, is verily the wise person. He indeed is spiritually integrated. He is verily the all-doer, all-performer.
Knowledgeable people call him Wise or Enlightened, whose all undertakings are freed of desire and imagination. His all actions are burnt by the fire of wisdom.
Leaving the delusional clinging to the results of karma, ever content, free of expectation, the one who engages in activities, verily does not do anything; he remains a non-doer.
Bereft of desires, with sufficient restraint over mind and senses, eschewing all kinds of gifts or gains, doing only bodily (physical) activities, one will not incur sin at all.
Content with whatever chance brings, rising above pairs of opposites, free of jealousy, equal in success and failure, one does not get bound by whatever he does.
Outliving delusional clinging, feeling liberated, mind fixed firmly on the Truth, whatever work is done with yajña attitude gets dissolved together with its result.
The act of offering is Brahman, the cooked rice offered is Brahman, the fire altar is Brahman, and the offerer too is Brahman. Brahman alone is to be attained by the mind as all activities get merged in Brahman.
Some Yogis make prescribed material offerings to various deities. Some others offer their yajña by yajña itself into the fire of Brahman.
Some offer the senses like the ear, meaning the sensory functions like hearing, seeing, smelling, etc., into the fire of their own restraint. Still others offer sound, hearing, etc. into the fire of their respective senses.
Others offer all sensory and vital activities into the fire of the yoga of inner discipline, lit by the fire of enlightenment.
Still others perform yajña with materials, some through austerity, some by yoga practice, as also by spiritual study and Vedic recitations observing rigid vows and restraint.
Some offer incoming breath (prāna) to outgoing breath (apāna), and the outgoing into the incoming. Restraining the incoming and the outgoing breaths alike, they pursue breath regulation, prāṇāyāma.
Others, disciplining their food, offer prāṇas into prāṇas (intense activities into reduced activity). All of them know the place and worth of yajña, and have their blemishes consumed by yajña.
Those who partake of the nectarine remains of yajña, reach the eternal Brahman. O best of Kurus, for one devoid of the yajña-spirit and pursuit, benefits of this world are not there; how then of the other.
Thus, manifold yajñas are prescribed in the scriptures. But, closely studied, all these are outcomes of karma alone. Knowing this truth, one attains freedom.
Jñāna-yajña, the sacrifice done through wisdom, is superior to the one in which materials are offered. All activities, O Partha, have their culmination in wisdom alone.
To gain that knowledge, go to the Knowers, who have the right vision of Truth; prostrate before them, inquire with humility, serve them fondly. They will instruct true knowledge to you.
By knowing which you will no more court any further delusion, and whereby you will see all beings in the Self and hence in Me, the Supreme.
Even if you are the most sinful of all sinners, by the raft of Knowledge you will cross the entire sea of sin.
Just as blazing fire reduces all the firewood into ash, the fire of Knowledge burns off all karmas into mere ash.
There is nothing in this world so purifying as jñāna. In due course of time, one will automatically attain it in himself, by dint of the maturity and fruition of yoga pursuit.
One imbued with interest in Brahman, with senses under control and assiduously attentive, begets knowledge. After gaining knowledge, he attains supreme peace before long.
The ignorant, inattentive and doubtful indeed perish. For the doubtful, neither this world nor the other, nor again happiness is there.
One, who has renounced all action through yoga, whose doubts are dispelled through spiritual wisdom, who is self-seated, O Dhananjaya, actions do not bind him.
Therefore, with the sword of spiritual knowledge, cut across this doubt of your heart caused by sheer ignorance, take to samatva-yoga and get up, O Bharata (Arjuna).
Om – the symbol of Brahman, tat – that singular Reality (Brahman), sat – the ever abiding presence (Brahman).
Thus ends the fourth chapter entitled Jñāna-karma-sannyāsa Yoga, during the Srikrishna-Arjuna dialogue in Śrīmad Bhagavad Gita, constituting Yoga-śāstra, which falls within Brahmavidya as presented in the Vedic Upanishads.
