King Māndhātā once said to Vasiṣṭha Muni, "O great sage, kindly be merciful to me and tell me of a holy fast that will benefit me eternally."
Vasiṣṭha Muni replied. "O king, kindly listen as I describe the best of all fast days, Āmalakī Ekādaśī. He who faithfully observes a fast on this Ekādaśī obtains enormous wealth, gets free of the effects of all kinds of sins, and attains liberation. Fasting on this Ekādaśī is more purifying than donating one thousand cows in charity to a pure brāhmana. So please hear me attentively as I tell you the story of a hunter who, though daily engaged in killing innocent animals for his living, achieved liberation by observing a fast on Āmalakī Ekādaśī following the prescribed rules and regulations of worship.
"There was once a kingdom named Vaidiṣā, where all the brāhmaṇas, kṣatriyas, vaiṣyas and śūdras were equally endowed with Vedic knowledge, great bodily strength, and fine intelligence. O lion among kings, the whole kingdom was full of Vedic sounds, not a single person was atheistic, and no one sinned. The ruler of this kingdom was King Pāśabinduka, a member of the dynasty of Soma, the moon. He was also known as Citraratha and was very religious and truthful. It is said that King Citraratha had the strength of ten thousand elephants and that he was very wealthy and knew the six branches of Vedic wisdom perfectly.
"During the reign of Mahārāja Citraratha, not a single person in his kingdom attempted to practice another's dharma so perfectly engaged in their own dharmas were all the brāhmaṇas, kṣatriyas, vaiṣyas and śūdras. Neither miser nor pauper was to be seen throughout the land, not was there ever a drought or flood. Indeed, the kingdom was free of disease, and everyone enjoyed good health. The people rendered loving devotional service to the Supreme Personality of God, Lord Viṣṇu, as did the king, who also rendered special service to Lord Śiva. Moreover, twice a month everyone fasted on Ekādaśī.
"In this way, O best of kings, the citizens of Vaidiṣā lived many long years in great happiness and prosperity. Giving up all varieties of materialistic religion, they completely dedicated themselves to the loving service of the Supreme Lord, Hari.
"Once, in the month of Phalguna, the holy fast of Āmalakī Ekādaśī arrived, conjoined with Dvādaśī. King Citraratha realised that this particular fast would bestow especially great benefit, and thus he and all the citizens of Vaidiṣā observed this sacred Ekādaśī very strictly, carefully following all the rules and regulations.
"After bathing in the river, the king and all his subjects went to the temple of Lord Viṣṇu, where an Āmalakī tree grew. First the king and his leading sages offered the tree a pot filled with water, as well as a fine canopy, shoes, gold, diamonds, rubies, pearls, sapphires, and aromatic incense. Then they worshiped Lord Paraśurāma with these prayers: 'O Lord Paraśurāma, O son of Reṇukā, O all-pleasing one, O liberator of the worlds, kindly come beneath this holy Āmalakī tree and accept our humble obeisances.' Then they prayed to the Āmalakī tree: 'O Āmalakī, O offspring of Lord Brahmā, you can destroy all kinds of sinful reactions. Please accept our respectful obeisances and these bumble gifts. O Āmalakī, you are actually the form of Brahman, and you were once worshiped by Lord Rāmacandra Himself. Whoever circumambulates you is therefore immediately freed of all his sins.'
"After offering these excellent prayers, King Citraratha and his subjects remained awake throughout the night, praying and worshiping according to the regulations governing a sacred Ekādaśī fast. It was during this auspicious time of fasting and prayer that a very irreligious man approached the assembly, a man who maintained himself and his family by killing animals. Burdened with both fatigue and sin, the hunter saw the king and the citizens of Vaidiṣā observing Āmalakī Ekādaśī by performing an all-night vigil, fasting, and worshiping Lord Viṣṇu in the beautiful forest setting, which was brilliantly illuminated by many lamps. The hunter hid nearby, wondering what this extraordinary sight before him was.
'What is going on here?' he thought. What he saw in that lovely forest beneath the holy Āmalakī tree was the Deity of Lord Dāmodara being worshiped upon the āsana of a waterpot, and what he heard were devotees singing sacred songs describing Lord Kṛṣṇa's transcendental forms and pastimes. Despite himself, that staunchly irreligious killer of innocent birds and animals spent the entire night in great amazement as he watched the Ekādaśī celebration and listened to the glorification of the Lord.
"Soon after sunrise, the king and his royal retinue - including the court sages and all the citizens -completed their observance of Ekādaśī and returned to the city of Vaidiṣā. The hunter then returned to his hut and happily ate his meal. In due time the hunter died, but the merit he had gained by fasting on Āmalakī Ekādaśī and hearing the glorification of the Supreme Personality of God, as well as by being forced to stay awake all night, made him eligible to be reborn as a great king endowed with may chariots, elephants, horses, and soldiers. His name was Vasūratha, the son of King Vidūratha, and he ruled over the kingdom of Jayantī.
"King Vasūratha was strong and fearless, as effulgent as the Sun, and as handsome as the Moon. In strength he was like Viṣṇu, and in forgiveness like the Earth itself. Very charitable and every truthful, King Vasūratha always rendered loving devotional service to the Supreme Lord, Śrī Viṣṇu. He therefore became very well versed in Vedic knowledge. Always active in the affairs of state, he enjoyed taking excellent care of his subjects, as though they were his own children. He disliked pride in anyone and would smash it when he saw it. He performed many kinds of sacrifices, and he always made certain that the needy in his kingdom received enough charity.
"One day, while hunting in the jungle, King Vasūratha strayed from the footpath and lost his way. Wandering for some time and eventually growing weary, he paused beneath a tree and, using his arms as a pillow, fell asleep. As he slept, some barbarian tribesmen came upon him and, remembering their longstanding enmity toward the king, began discussing among themselves various ways to kill him. 'It is because he killed our fathers, mothers, brothers-in-law, grandsons, nephews, and uncles that we are forced to aimlessly wander like so many madmen in the forest.' So saying, they prepared to kill King Vasūratha with various weapons, including spears, swords, arrows and mystic ropes.
"But none of these deadly weapons could even touch the sleeping king, and soon the uncivilised, dog-eating tribesmen grew frightened. Their fear sapped their strength, and before long they lost what little intelligence they had and became almost unconscious with bewilderment and weakness. Suddenly a beautiful woman appeared from the king's body, startling the aborigines. Decorated with many ornaments, emitting a wonderful fragrance, wearing an excellent garland around her neck, her eyebrows drawn in a mood of fierce anger, and her fiery red eyes ablaze, she looked like death personified. With her blazing chakra discus she quickly killed all the tribal hunters, who had tried to slay the sleeping king.
"Just then the king awoke, and seeing all the dead tribesmen lying around him, he was astonished. He wondered, 'These are all great enemies of mine! Who has slain them so violently? Who is my great benefactor?'
"At that very moment he heard a voice from the sky: 'You ask who helped you. Well, who is that person who alone can help anyone is distress? He is none other than Śrī Keśava, the Supreme Personality of God, He who saves all who take shelter of Him without any selfish motive.'
"Upon hearing these words, King Vasūratha became over-whelmed with love for the Personality of God. He returned to his capital city and ruled there like a second Indra, without any obstacles at all.
"Therefore, O King Māndhātā," the venerable Vasiṣṭha Muni concluded, "...anyone who observes this holy Āmalakī Ekādaśī will undoubtedly attain the supreme abode of Lord Viṣṇu, so great is the religious merit earned from the observance of this most sacred fast day."
Thus ends the Vṛjavāsī narration of the glories of Phālguna-sukla Ekādaśī, or Āmalakī Ekādaśī, from the Brahmāṇḍa Purāṇa.
