As the conversation between Arjuna and Krishna continued on the battlefield of Kurukshetra, Krishna began to explain to Arjuna the profound meanings behind certain words and actions. He told Arjuna that the word ‘Sat’ signifies reality and goodness, and is applied to actions that are praiseworthy. Moreover, steadfastness in sacrifice, austerity, and charity are also called ‘Sat’, and any action undertaken for these purposes is likewise designated as ‘Sat’. However, Krishna cautioned that whatever is offered, given, or performed as austerity or any act without faith is called ‘asat’; such action is neither fruitful in this world nor in the world beyond. At this point, Arjuna, eager to understand more, asked Krishna, “O mighty-armed one, I wish to know the truth of renunciation and abandonment, O Hrishikesha, and the distinction between them, O slayer of Keshin.” Krishna replied, “The wise understand renunciation as the giving up of actions performed with desire, while the learned declare abandonment to be the relinquishing of the fruits of all actions. Some thinkers say that action itself should be abandoned as evil, but others insist that acts of sacrifice, charity, and austerity should not be given up. Now listen to my final judgment about abandonment, O best of the Bharatas. Abandonment is declared to be of three kinds. Acts of sacrifice, charity, and austerity are not to be abandoned; they must be performed, for they are purifying even for the wise. Yet even these actions should be done without attachment and without desire for their results. This, O Partha, is my firm and best judgment. The renunciation of prescribed action is not proper; to abandon such action out of delusion is considered to be of the nature of darkness. If action is abandoned merely because it is painful or out of fear of bodily discomfort, such abandonment is of the nature of passion, and one does not obtain the fruit of renunciation thereby. But prescribed action performed simply because it ought to be done, giving up attachment and desire for results, that renunciation is of the nature of goodness. The person who is pure, wise, and free from doubt neither hates unskillful action nor becomes attached to skillful action. Such a renouncer is established in goodness. Indeed, it is not possible for one who possesses a body to completely give up all actions; but whoever gives up the fruits of actions, that person is truly called a renouncer. The threefold fruit of action—undesirable, desirable, and mixed—comes to those who do not renounce, after death; but never to those who are renunciants. O mighty-armed one, now learn from me the five causes necessary for the accomplishment of all actions, as declared in the philosophy of knowledge. They are: the body as the seat of action, the agent, the various instruments, the different kinds of activities, and the divine as the fifth. Whatever action a person undertakes with body, speech, or mind—whether just or unjust—these five are its causes. Therefore, whoever, due to unrefined understanding, sees the self alone as the agent, does not see truly and is of distorted intellect. Whoever is free from the sense of ego and whose understanding is not tainted—even if such a person kills all these people—neither kills nor is bound. Knowledge, the object of knowledge, and the knower are the threefold incitements to action; the instrument, the action, and the agent are the threefold constituents of action. Knowledge, action, and the agent are declared to be of three kinds according to the difference of the qualities—hear them as they are. That knowledge by which one sees the one imperishable reality in all beings, undivided in the divided—know that knowledge to be of the nature of goodness. Knowledge by which one sees various kinds of beings as distinct and separate in all creatures is of the nature of passion. Knowledge attached to a single effect as if it were the whole, without reason, lacking in truth, and trivial, is declared to be of the nature of darkness. Action that is prescribed, performed without attachment, without desire or aversion, and without longing for its result, is of the nature of goodness. Action performed with desire for its result, or with pride, and with great effort, is of the nature of passion. Action undertaken out of delusion, without regard for consequences, loss, harm, or one’s own ability, is of the nature of darkness. The agent who acts without attachment, without asserting ‘I am the doer,’ endowed with firmness and enthusiasm, and remains unchanged in success or failure, is called a sattvic agent. The agent who is passionate, eager for the fruits of action, greedy, violent, impure, and subject to joy and sorrow, is declared rajasic. The agent who is unfit, crude, arrogant, deceitful, malicious, lazy, despondent, and procrastinating is called tamasic. Now, O Dhananjaya, hear the threefold distinction of intellect and resolve according to the qualities. The intellect which knows action and inaction, what ought to be done and what ought not, fear and fearlessness, bondage and liberation, is sattvic. The intellect by which one incorrectly understands righteousness and unrighteousness, what ought to be done and what ought not, is rajasic. The intellect which, enveloped in darkness, regards unrighteousness as righteousness and perceives all things in a distorted way, is tamasic. The firmness by which one sustains the functions of mind, life, and senses through unwavering yoga is sattvic. The firmness by which one holds to righteousness, desire, and wealth, seeking their results with attachment, is rajasic. The firmness by which a person of poor understanding does not let go of sleep, fear, sorrow, despondency, and arrogance is tamasic. Now hear from me, O best of Bharatas, the threefold happiness. The happiness in which one delights through practice and attains the end of sorrow, which at first seems like poison but in its result is like nectar, is sattvic, born of clarity in self-understanding. That happiness which at first is like poison but in its outcome is like nectar is declared sattvic, arising from the serenity of self-understanding. Thus, Krishna revealed to Arjuna the subtle distinctions of action, knowledge, agents, intellect, resolve, and happiness, showing how each is shaped by the qualities of goodness, passion, and darkness, and guiding him toward the path of wisdom and renunciation.
