Overwhelmed by desire and passion, the eminent sage Viśvāmitra found himself beset by an obstacle that filled him with deep remorse. Sighing heavily, he gazed upon the fearful apsaras Menakā, who stood before him trembling, her hands joined in supplication. Moved by compassion, Kuśika’s son gently released her, speaking kind words to ease her distress. Determined to overcome his own weaknesses, Viśvāmitra resolved to conquer himself and departed for the northern mountains, his heart set upon unshakable austerity. There, on the sacred banks of the Kauśikī river, he undertook a fierce and nearly impossible penance, practicing severe austerities for thousands of years. As Viśvāmitra’s tapas blazed forth on the northern mountain, fear arose among the gods. Disturbed by his growing power, all the gods, together with the hosts of sages, gathered and consulted with one another. They agreed, “Let Kuśika’s son attain the title of great sage.” Their decision reached Brahmā, the grandfather of all worlds, who approached Viśvāmitra and addressed him with sweet words: “Welcome, O child! Your intense penance has pleased me. I grant you greatness and the foremost status among sages, O Kauśika.” Hearing these words, Viśvāmitra, his austerities still vibrant within him, bowed with joined palms and spoke humbly to Brahmā: “If you, O Lord, declare for me the incomparable title of Brahmarṣi, earned by my own virtuous deeds, then truly I shall be one who has conquered the senses.” But Brahmā replied, “You have not yet conquered the senses. Strive further, O tiger among sages.” With these words, Brahmā departed to heaven. Left alone, Viśvāmitra redoubled his efforts. With arms raised and unsupported, he sustained himself on nothing but air. In the heat of summer, he stood amidst five blazing fires; in the rains, he remained exposed to the sky; and through the cold of winter, he lay in water by day and night. For yet another thousand years, he subjected himself to terrible austerities. But as Viśvāmitra’s penance grew ever more intense, the gods and Indra became greatly distressed. Seeking to disrupt his tapas, Indra, accompanied by the Maruts, summoned the apsaras Rambhā. “O Rambhā,” he said, “the gods have a great task for you. You must entice Kauśika, filling him with desire and delusion.” Bashful and fearful, Rambhā replied with joined palms, “O lord of the gods, this Viśvāmitra is terrible in his ascetic power. Without doubt, he will unleash dreadful anger upon me. Therefore, I am afraid; grant me your favor, O god.” Indra reassured her: “Do not fear, Rambhā. All will be well. Carry out my command. In the beauty of spring, amidst blossoming trees, I will remain by your side with Kāma, and the song of the cuckoo will captivate his heart. Adorned with your radiant beauty and many charms, you must disturb the sage’s devotion.” Encouraged by Indra’s words, Rambhā assumed a form of unsurpassed beauty and began to entice Viśvāmitra. The sweet voice of the cuckoo filled the air, and Viśvāmitra’s mind was momentarily delighted as he gazed upon Rambhā’s lovely form. But soon, suspicion arose in his heart—he perceived this as Indra’s doing. Seized by anger, the sage cursed Rambhā: “Because you tempt me, Rambhā, who seeks victory over desire and anger, you shall stand as a stone for ten thousand years. Only a brāhmaṇa of great splendor and ascetic power will deliver you from this curse.” With the utterance of his words, Rambhā was instantly transformed into stone, and Kāma departed, hearing the sage’s wrath. Yet Viśvāmitra was left troubled, overcome by anger and the loss of his ascetic power. Realizing that his senses were not yet fully mastered, he found no peace within himself. His mind disturbed by the disruption of his penance, he resolved, “I will not give in to anger, nor will I speak in any way. I shall not even breathe for hundreds of years, but will dry up myself, having conquered my senses. Until I attain the status of a Brāhmaṇa, earned through asceticism, I will remain without breathing or eating for countless years. While I practice these austerities, my bodily form will not perish.” Thus, for another thousand years, Viśvāmitra undertook an unparalleled vow, unmatched in the world. When this period ended, the great sage left the Himalayan region, journeyed eastward, and performed even more severe austerities. He maintained a vow of silence for a thousand years, practicing an incomparable and supremely difficult asceticism. When these thousand years were complete, Viśvāmitra—now like wood, battered by countless obstacles—did not allow anger to enter his heart. Thus, through endless trials and steadfast resolve, Viśvāmitra continued his journey, ever striving for mastery over himself and the highest spiritual attainment.
