Hear now the sacred teaching as Lord Krishna speaks to Arjuna, revealing the profound mysteries of the soul’s journey and the supreme goal sought by the wise. Krishna begins by describing that imperishable state—the ultimate destination—which is extolled by the knowers of the Vedas, entered by ascetics free of passion, and pursued by those who practice celibacy with steadfast intent. Out of compassion, Krishna promises to explain this supreme goal briefly and clearly. He tells Arjuna that one must restrain all the gates of the senses, confining the mind within the heart, and fixing the life-breath at the crown of the head, all while remaining absorbed in the unwavering practice of yoga. At the time of leaving the body, one who utters the sacred syllable “Om”—which is Brahman itself—and remembers Krishna, attains the highest destination. Krishna assures Arjuna that for the yogi who remembers Him constantly, with a mind undistracted, He is easily attained, for such a soul remains ever united with Him. Those great souls, having reached Krishna and attained the supreme perfection, are freed from the cycle of birth and death; they do not return to this world of sorrow and impermanence. Even the highest realms, up to the world of Brahma, are subject to repeated return, Krishna explains, but upon reaching Him, there is no rebirth. He reveals the vastness of cosmic time: those who truly understand know that a single day of Brahma lasts for a thousand ages, and his night, too, endures for a thousand ages. When Brahma’s day arrives, all beings emerge from the unmanifest; when night falls, they dissolve back into that very unmanifest source. This cycle repeats endlessly: at the coming of night, all beings are dissolved, and with the coming of day, they arise again, compelled by the force of nature. Yet, Krishna declares, there exists another unmanifest beyond this, eternal and imperishable, which remains untouched even when all beings are destroyed. This supreme unmanifest is called the imperishable, the highest goal. Having attained it, none return; it is Krishna’s own supreme abode. This highest Person, Krishna tells Arjuna, is reached through exclusive devotion. All beings dwell within Him, and by Him all creation is pervaded. Krishna then offers to explain the secret of the soul’s departure: at what times yogis leave, never to return, and at what times they return again. Those who depart during times of light—fire, day, the bright fortnight, and the six months of the sun’s northern course—knowing Brahman, attain Brahman and do not return. Those who depart during times of smoke, night, the dark fortnight, and the six months of the southern course reach the lunar light and are reborn. Thus, these two paths—bright and dark—are eternal. By one, souls go and do not return; by the other, they return again. Knowing these truths, no yogi is ever deluded. Therefore, Krishna urges Arjuna to remain ever steadfast in yoga. The yogi who understands all this surpasses even the fruits of Vedic rituals, sacrifices, austerities, and charity, and attains the supreme, primordial abode. Having thus spoken, Krishna reveals an even deeper mystery. “Now, Arjuna, I shall declare to you, who are free from envy, the most secret knowledge, together with realization. By knowing this, you shall be freed from all evil.” He describes this wisdom as the king of knowledge and the king of secrets—supremely pure, the highest, directly experienced, righteous, easy to practice, and imperishable. Yet, Krishna laments, those without faith in this dharma, failing to reach Him, must return to the path of birth and death. He explains that, though His unmanifest form pervades the entire world and all beings are in Him, He is not bound or limited by them. Beings do not truly dwell in Him—this is His divine mystery. Though He upholds all beings and is their source, His true Self remains unattached. To help Arjuna understand, Krishna gives the example of the mighty wind, which moves everywhere but rests in space. In the same way, all beings exist in Him. At the end of each cosmic age, all beings merge into Krishna’s own nature; when a new cycle begins, He sends them forth again. Holding His own nature, He sends forth this multitude of beings, who act according to the compulsion of nature. Yet, these actions do not bind Him—He remains indifferent, unattached. By His supervision, nature gives birth to all things, both moving and unmoving; thus the world revolves, sustained by His will. But fools, Krishna says, fail to recognize Him when He assumes a human form, not knowing His higher nature as the great Lord of all beings. Such deluded ones, vain in their hopes, actions, and knowledge, take refuge in demonic and deluding natures. But the great-souled, who take refuge in the divine, worship Krishna with unwavering minds, knowing Him as the imperishable origin of all beings. Always glorifying Him, striving with firm resolve, bowing in devotion, they worship Him ever steadfast. Others, too, worship Krishna in various ways, performing the sacrifice of knowledge—seeing Him as one, as many, and in all forms, facing everywhere. Krishna then declares, “I am the ritual, the sacrifice, the offering to the ancestors, the healing herb, the mantra, the clarified butter, the fire, and the act of offering. I am the father of this world, the mother, the supporter, the grandsire. I am the object of knowledge, the purifier, the syllable Om, and also the Rig, Sama, and Yajur Vedas. I am the goal, the sustainer, the Lord, the witness, the abode, the refuge, the friend. I am the origin, the dissolution, the foundation, the treasure, and the imperishable seed. I give heat, I withhold and send forth the rain. I am immortality and also death, both being and non-being.” He explains that those who know the three Vedas, purified by soma, worship Him with sacrifices, seeking the path to heaven. Attaining the world of Indra, they enjoy the pleasures of the gods. Yet, when their merit is exhausted, they return to the mortal world; thus, following the path of the Vedas and seeking desires, they come and go. But those who, meditating on Krishna alone, worship Him with undivided devotion—He brings them what they lack and preserves what they have, ever caring for His steadfast devotees. Thus, Krishna reveals to Arjuna the deepest truths of existence: the cycle of creation and dissolution, the supreme abode, the mystery of His all-pervading presence, and the path to liberation through unwavering devotion.
