Krishna continued to speak to Arjuna, illuminating the nature of happiness itself. He explained that some happiness arises when the senses meet their objects—a pleasure that seems sweet as nectar at first, but in the end brings bitterness, like poison. This, Krishna said, is the happiness born of passion, rajasic in nature. Other kinds of happiness, Krishna revealed, deceive the soul from the very beginning and in their effect. They spring from sleep, laziness, and negligence, casting a veil over the mind. Such happiness is known as tamasic, rooted in darkness and ignorance. Krishna then declared a profound truth: there is no being on earth, nor among the gods in heaven, who is free from these three qualities—sattva, rajas, and tamas—that are born of nature itself. Turning to the duties of humankind, Krishna addressed Arjuna as Parantapa, the scorcher of foes, and explained that the responsibilities of Brahmins, Kshatriyas, Vaishyas, and Shudras arise from the qualities inherent in their own nature. He described the natural duties of the Brahmin: tranquility, self-control, austerity, purity, patience, uprightness, knowledge, wisdom, and faith. For Kshatriyas, the duties are valor, strength, steadfastness, skill, not fleeing from battle, generosity, and a regal bearing. The Vaishyas are called to farming, the protection of cows, and trade, while the Shudras’ natural duty is service. Krishna assured Arjuna that anyone who is devoted to their own duty attains perfection. He urged Arjuna to listen as He revealed how one who dedicates themselves to their own work can achieve success. By worshipping, through one’s own work, the source from which all beings arise and by which all creation is pervaded, a person attains perfection. Krishna emphasized that it is better to perform one’s own duty, even if imperfectly, than to do another’s duty well. By acting according to one’s own nature, one does not incur sin. Even if the work born of one’s own nature is flawed, it should not be abandoned, Krishna told Arjuna. All actions are touched by some imperfection, just as fire is veiled by smoke. Krishna then described the path of renunciation: the one whose intellect is unattached everywhere, who has mastered himself and is free from desire, attains the supreme perfection of actionlessness. He invited Arjuna to hear, in brief, how one who has reached perfection attains Brahman, the highest knowledge. Such a person, Krishna said, is endowed with a purified intellect, controls himself with firmness, gives up the objects of the senses, and abandons attachment and aversion. They dwell in solitude, eat lightly, govern speech, body, and mind, remain steadfast in meditation, and embrace detachment. By giving up ego, strength, arrogance, desire, anger, and possessiveness, and by becoming free from the sense of ‘mine’ and attaining peace, one becomes fit for union with Brahman. Upon becoming one with Brahman, the soul becomes cheerful, free from grief and desire, and views all beings with equal vision. Such a one attains supreme devotion to Krishna Himself. Through devotion, one comes to know Krishna truly—who He is and what He is. Having known Him thus, one enters into Him at once. Even while performing all actions, if one takes refuge in Krishna, by His grace one attains the eternal, imperishable state. Krishna urged Arjuna to surrender his mind to Him, to make Him the supreme goal, to rely on the yoga of intellect, dedicate all actions to Him, and remain absorbed in Him always. With the mind thus fixed, Krishna promised that by His grace, Arjuna would overcome all difficulties. But Krishna also warned that if, out of pride, Arjuna refused to listen, he would be lost. If, relying on ego, Arjuna thought, “I will not fight,” this resolve would be in vain, for his own nature would compel him to act. Bound by his own actions, born of his nature, Arjuna would do—even unwillingly—what he did not wish to do, deluded by ignorance. Krishna revealed a final, profound truth: the Lord dwells in the hearts of all beings, O Arjuna, causing all to move as if mounted on a machine, by His power of illusion. Therefore, Krishna urged, Arjuna should take refuge in Him alone, with all his being. By Krishna’s grace, Arjuna would attain supreme peace and the eternal abode. Having thus imparted the most secret knowledge, Krishna encouraged Arjuna to reflect deeply and then act as he wished. Yet, out of love, Krishna spoke again: “Hear My supreme word, the most confidential of all, for you are dearly beloved to Me. Fix your mind on Me, become My devotee, worship Me, bow to Me, and you will surely come to Me. I promise you truly, for you are dear to Me.” Krishna then gave the highest assurance: “Abandon all duties and take refuge in Me alone. I will liberate you from all sins; do not grieve.” He cautioned, however, that this teaching should not be given to those without austerity, devotion, willingness to listen, or to those who mock Him. Whoever shares this supreme secret among Krishna’s devotees, with devotion established in Him, will surely come to Him. Among all people, Krishna said, there is none dearer to Him than such a one, nor will there ever be anyone dearer on earth. Even those who study this sacred dialogue between Krishna and Arjuna are, in Krishna’s eyes, worshipping Him through the sacrifice of knowledge. Whoever hears it with faith and without malice will be freed and will attain the blessed worlds of the righteous. At last, Krishna asked, “O Partha, have you listened with a focused mind? Has your ignorance and confusion been dispelled, O Dhananjaya?” Arjuna replied with a clear heart: “My delusion is gone, and my memory has been restored by Your grace, O Achyuta. I am firm, free from doubt, and I will act according to Your word.” Sanjaya, who witnessed this divine exchange, then spoke: “Thus I have heard this wondrous and thrilling dialogue between Vasudeva and the great-hearted Partha. By the grace of Vyasa, I have heard this supreme secret, the yoga spoken directly by Krishna, the Lord of Yoga. O King, remembering again and again this holy and marvelous conversation between Keshava and Arjuna, I rejoice again and again. And as I recall the most glorious form of Hari, I am filled with awe and joy, again and again.
