Arjuna listened intently as Lord Krishna continued to illuminate the path of renunciation and action. Krishna explained that when a person abandons their duties simply because they are painful or out of fear of bodily discomfort, such abandonment is born of passion. This kind of renunciation, Krishna said, does not bring the true fruit of letting go. In contrast, when one performs the actions that are prescribed—doing them simply because they ought to be done, without attachment or desire for their results—that is renunciation in the mode of goodness. Krishna described the person established in this goodness: pure of heart, wise, and free from doubt. Such a renouncer neither hates unskillful action nor becomes attached to skillful deeds. Indeed, Krishna reminded Arjuna, it is not possible for a person with a body to completely give up all actions. But the true renouncer is one who relinquishes the fruits of their actions, not the actions themselves. For those who do not renounce, the results of action—whether pleasant, unpleasant, or mixed—follow them even after death. But the renunciant, having let go of attachment to results, is untouched by such consequences. “O mighty-armed Arjuna,” Krishna continued, “hear from me about the five causes necessary for the accomplishment of all actions, as declared in the philosophy of knowledge. These are: the body, which is the seat of action; the individual agent; the various instruments of action; the many kinds of activities; and, as the fifth, the divine presence itself. Every action performed—by body, speech, or mind, whether just or unjust—has these five as its causes.” Krishna warned that those who, out of unrefined understanding, see the self alone as the agent of action do not see truly; their intellect is distorted. But one who is free from ego and whose understanding is pure—even if such a person were to slay all these people—neither kills nor is bound by the act. He explained further: knowledge, the object known, and the knower—these three prompt action. Similarly, the instrument, the action, and the agent are the threefold constituents of action. Knowledge, action, and the agent are each of three kinds, shaped by the qualities of nature—goodness, passion, and darkness. Krishna urged Arjuna to listen carefully as he explained them. Knowledge of the highest kind is that by which one sees the one imperishable reality in all beings—undivided amidst the divided. This is knowledge in the mode of goodness. Knowledge that sees beings as separate and distinct is of the nature of passion. But knowledge that clings to a single effect as if it were the whole, lacking reason, truth, and depth, is of the nature of darkness. Similarly, action that is prescribed, performed without attachment, without desire or aversion, and without longing for its result, is of goodness. Action performed with desire for results, with pride, and with great effort, is of passion. Action undertaken out of delusion, without considering consequences, loss, harm, or one’s own ability, is of darkness. Krishna described the different types of agents: the sattvic agent acts without attachment, does not claim “I am the doer,” is firm and enthusiastic, and remains unchanged in success or failure. The rajasic agent is passionate, eager for fruits, greedy, violent, impure, and swayed by joy and sorrow. The tamasic agent is unfit, crude, arrogant, deceitful, malicious, lazy, despondent, and procrastinating. “Now, Arjuna, hear of the threefold distinction of intellect and resolve, according to the qualities,” Krishna said. The sattvic intellect knows what is action and what is inaction, what should and should not be done, fear and fearlessness, bondage and liberation. The rajasic intellect is clouded, misunderstanding righteousness and unrighteousness, what should be done and what should not. The tamasic intellect, enveloped in darkness, sees unrighteousness as righteousness and perceives all things in a distorted way. Firmness, too, is threefold. Sattvic firmness sustains the functions of the mind, life, and senses through unwavering yoga. Rajasic firmness clings to righteousness, desire, and wealth, seeking their results with attachment. Tamasic firmness refuses to let go of sleep, fear, sorrow, despondency, and arrogance. Krishna then explained the threefold happiness, urging Arjuna to listen. Sattvic happiness comes from self-understanding and practice. Though it may seem like poison at first, in its result it is like nectar, for it brings an end to sorrow. Rajasic happiness arises from contact between the senses and their objects; it appears sweet at first, but in the end is like poison. Tamasic happiness, born of sleep, laziness, and negligence, deludes from the beginning and in its effect. “No being on earth, nor even among the gods in heaven, is free from these three qualities of nature,” Krishna declared. He went on to explain the duties assigned to each class, arising from their nature: the Brahmin’s duties are tranquility, self-control, austerity, purity, patience, uprightness, knowledge, wisdom, and faith. The Kshatriya’s duties are valor, strength, firmness, skill, not fleeing in battle, generosity, and lordliness. The Vaishya’s duties are farming, cow protection, and trade. The Shudra’s duty is service. Krishna emphasized that by being devoted to one’s own duty, a person attains perfection. He explained that by worshipping the source from which all beings arise and by which all is pervaded—through one’s own work—a person reaches perfection. “Better to do one’s own duty, even if imperfectly, than to do another’s duty well,” Krishna counseled. “By acting according to one’s own nature, one does not incur sin.” Thus, Krishna revealed to Arjuna the profound distinctions of action, renunciation, knowledge, agent, intellect, resolve, happiness, and duty, all according to the three qualities of nature, guiding him toward the highest good.
