In a time of great turmoil, a sage named Ruru found himself in a dire situation. Filled with a deep sense of anger and vengeance, he confronted a serpent, believing it to be the one responsible for a grievous wrong against him. "O possessor of austerities," he exclaimed, "I have done you no wrong today; then why, filled with anger, do you wish to strike me?" The serpent, known as Dundubha, sensed the gravity of the moment. Ruru, driven by the pain of losing his beloved wife to a serpent's bite, had made a dreadful vow to slay every serpent he encountered. "I vowed to slay every serpent I see; therefore, I seek to kill you now—you shall lose your life today," he declared, his heart heavy with sorrow and rage. Yet, as Ruru stood poised to strike, Dundubha spoke with a calm wisdom that pierced through the haze of Ruru's fury. "Other serpents have bitten humans here, O Ruru, but you, who bear the scent of a Dundubha, do not deserve to be harmed. There are various harms, different duties, many sorrows, and separate joys; being one who knows righteousness, you do not deserve to be harmed." Hearing these words, Ruru, recognizing the sage within the serpent, hesitated, his fear giving way to respect. "Tell me, serpent," Ruru inquired gently, "by what cause have you come to this state, and who are you?" The serpent revealed a profound truth, "I was once the sage named Ruru, with a thousand feet; by the curse of a Brahmin, I have come to take the form of a serpent." Ruru's heart sank as he listened to the tale of the curse that had transformed the sage into a serpent. The serpent continued, recounting his past friendship with a Brahmin named Khagama. In their childhood, a playful jest had gone awry when Ruru fashioned a serpent from grass, causing Khagama to faint in fear. Upon regaining consciousness, the angry Brahmin cursed Ruru to take the form of a serpent, equal in strength to the fear he had instilled. "But listen to what I shall say to you, O ascetic," Dundubha urged. "A pure son named Ruru will be born to Pramati; upon seeing him, your curse will be released, and not long after." As the serpent spoke, he revealed his true identity as the illustrious Brahmin sage, who had regained his radiant form. "Non-injury is the highest dharma, O best among all living beings," he imparted to Ruru. "Therefore, a Brahmin should never harm any living creature; the supreme teaching here is that a Brahmin is gentle." He went on to explain the distinct duties of the Kshatriya and Brahmin, emphasizing that while the Kshatriya bears the rod of authority, a Brahmin must embody gentleness and compassion. The sage then spoke of the great sacrifice of King Janamejaya, where serpents had been harmed, but also of the wise Astika, who had intervened to protect the frightened serpents. "How did King Janamejaya harm the snakes? And why were the snakes harmed there?" Ruru asked, eager to understand the full story. "You will hear, Ruru, the entire great story of Astika, as told by the Brahmins," the sage replied, his voice resonating with urgency. "But I must depart." With that, the illustrious sage vanished through his yogic power, leaving Ruru in a state of amazement. Driven by a mix of awe and determination, Ruru searched for the sage, but his strength waned, and he fell to the ground, lost in contemplation of the sage’s profound words. Regaining consciousness, Ruru rushed to his father, sharing the meaningful revelations of Dundubha. He questioned his father further about Astika’s words, eager to grasp the truth behind the tale. Ruru's father, filled with wisdom, recounted the story of King Janamejaya and the destruction of the snakes during the sacrifice. "Why did that tiger among kings seek the destruction of the snakes?" Ruru implored, his curiosity ablaze. "And for what reason did Astika, the wise, release the serpents?" The answers lay in the depths of the past, waiting to be uncovered, as Ruru listened intently, yearning to understand the intricate tapestry of fate and dharma that bound them all together.
