In the sacred discourse between sage Agastya and King Bhadrāśva, the sage began by describing the observances of profound vows. He instructed that the wise should begin their vow in the bright fortnight of Phālguna, noting especially that the fierce vow is performed on the fourteenth day of the dark fortnight, starting from the month of Māgha, and continued for a full year. On the fifteenth day of the bright fortnight, the moon vow is to be observed by eating only at night, while the ancestral vow is performed on the new moon—such is the prescription for the devout. King Bhadrāśva, curious about the fruits of such discipline, asked what reward awaits those who practice these lunar vows for five or ten years. Agastya replied that performing these vows is equal to thousands of Ashvamedha sacrifices and hundreds of Rājasūya rituals, as well as all other rites prescribed in the scriptures. However, even a single violation destroys the vow and brings constant sin. But one who completes these vows entirely becomes pure, free from stain, and attains all the worlds. Moved by these teachings, Bhadrāśva then asked Agastya to recount any marvels he might know. Agastya replied that the Blessed Lord Janārdana himself is the source of all wonders, and many marvelous deeds of his have been witnessed. He narrated a tale of the sage Nārada, who once journeyed to the realm of Shvetadvīpa. There, Nārada beheld radiant men bearing the conch, discus, and lotus, each blazing with intense light. Amazed, Nārada thought, “This is Viṣṇu, this is Viṣṇu, this is the eternal Viṣṇu,” but he was perplexed as to which among them was truly the Lord. As Nārada pondered, his thoughts turned to Kṛṣṇa and he wondered how he might worship the true bearer of the conch, discus, and mace. Desiring to know which among them was the supreme Lord Nārāyaṇa, he began to meditate deeply on that Supreme Being. For a thousand divine years, the son of Brahmā meditated, until the Lord was pleased and appeared before him with a gracious heart. The Lord said, “O son of Brahmā, ask for a boon—what shall I grant you, great sage?” Nārada replied, “O Lord of the world, I have meditated on you for a thousand years. If you are pleased with me, O Achyuta, tell me how you may be attained.” The Lord answered, “Those twice-born who worship me by following the Puruṣa Sūkta or the original Saṃhitā will attain me, O Nārada. If the Vedic scriptures are not available, people may reach me by the path of the Pañcarātra. This path is prescribed for Brahmins, Kṣatriyas, and Vaiśyas; it is not for Śūdras or others. In ancient times, I declared that if anyone among thousands accepts the Pañcarātra, and at the end of his actions becomes my devotee, then this Pañcarātra will always abide in his heart. Others, enveloped by royal and tamasic dispositions, will turn away from my command. In the Kṛta, Tretā, and Dvāpara yugas, those established in sattva will reach me, but in Kali, rajas and tamas will predominate. Now, I grant you another boon, Nārada: by my grace, you shall know all of this Pañcarātra, my exceedingly rare scripture. Know that I am attained only through the Veda, the Pañcarātra, devotion, and sacrifice—not otherwise, even in ten million years.” Having spoken thus, the Supreme Lord vanished, and Nārada ascended to heaven. Bhadrāśva then asked Agastya about the mysteries of the world: “Who are the two women, one white and one black, said to be separate in the world? Who is the man who becomes one and then sevenfold? Who is the twice-bodied, six-headed, twelvefold lord? What is the union of husband and wife, and the eating after sunrise? Why is this world so spread out?” Agastya explained, “The two women, one white and one black, are sisters—night is declared to be the woman of two colors, representing truth and untruth. The man who, though one, is born sevenfold, is the ocean, existing as one in seven forms. The twelvefold lord with two bodies and six faces is the year; the two bodies are its two courses, and the six mouths are the six seasons. The union of husband and wife is day and night; from them arose the sun and moon, and from them this world came forth. That Viṣṇu, the supreme god, is to be known, and one without Vedic rites does not behold the Supreme Lord.” Again, Bhadrāśva inquired, “How is that supreme and non-supreme Viṣṇu to be understood in each of the four ages? What will be the conduct of the castes, and what will become of the purity of Brāhmaṇas when there is intermixture?” Agastya answered, “In the Kṛta age, the earth is enjoyed by the gods through Vedic rites; in the Tretā age, it is likewise enjoyed by those who perform sacrifices and by the gods. In the Dvāpara age, when sattva and rajas are predominant, the earth is enjoyed as long as the king, son of Dharma, exists. But then darkness will prevail in the form of Kali, and in that age, the twice-born will deviate from their own path. Kings, Vaiśyas, and Śūdras will mostly be of low birth, lacking truth and purity. The twice-born will approach the unapproachable, speak falsehood, abandon the Vedic path, and intermarry without regard for lineage. Kings, greedy for wealth and deceitful, will harm Brāhmaṇas; outcastes will assume the status of Vaiśyas, delighting in trade, and those of Śūdra birth will become proud and arrogant.” Thus, Agastya imparted to Bhadrāśva the mysteries of vows, the wonders of the Lord, the nature of time, and the transformations of the ages, all as revealed by the ancient scriptures.
