Mohini Ekadashi occurs during the waxing phase of moon in the month of Vaisakha (April – May). The greatness of this Ekadasi was explained by Vasistha to Lord Ram; also Lord Krishna narrated it to Yudishitira, the eldest of the Pandavas. In 2010, the date of Mohini Ekadasi is May 24.

Yudhisthira Maharaja said, "0 Janardana, what is the name of the Ekadasi that occurs during the light fortnight of the month of Vaisakha [AprilMay]? What is the process for observing it properly? Kindly narrate all this to me."

Lord Sri Krishna replied, "0 blessed son of Dharma, what Vasistha Muni once told Lord Ramacandra I shall now describe to you. Please hear Me attentively.

"Lord Ramacandra asked Vasistha Muni, '0 great sage, I would like to hear about the best of all fasting days-that day which destroys all kinds of sins and sorrows. I have suffered long enough in separation from My dear Sita, and so I wish to hear from you about how My suffering can be ended.'

"The sage Vasistha replied, '0 Lord Rama, 0 You whose intelligence is so keen, simply by remembering Your name one can cross the ocean of this material world. You have questioned me in order to benefit all of humanity and fulfill everyone's desires. I shall now describe that day of fasting which purifies the whole world.

'0 Rama, that day is Vaisakha-sukla Ekadasi. It removes all sins and is famous as Mohini Ekadasi, Truly, 0 Rama, the merit of this Ekadasi frees the fortunate soul who observes it from the network of illusion. Kindly listen as I describe its glories, because for one who even just hears about this auspicious Ekadasi, the greatest sins are nullified.

"'On the banks of the Sarasvati River there was once a beautiful city named Bhadravati, which was ruled by King Dyutiman. 0 Rama, that steadfast, truthful, and highly intelligent king was born in the dynasty of the moon. In his kingdom was a merchant named Dhanapala, who possessed a great wealth of food grains and money. He was also very pious.He was an excellent devotee of Shree Hari and had five sons: Sumana, Dyutiman, Medhavi, Sukrti, and Dhrstabuddhi.

"'Unfortunately, his son Dhrstabuddhi always engaged in greatly sinful activities, such as sleeping with prostitutes and associating with degraded persons. He enjoyed gambling, and many other varieties of sense gratification. He disrespected the demigods; brahmanas; forefathers and other elders; and his family's guests. The evilhearted Dhrstabuddhi spent his father's wealth indiscriminately, always feasting on untouchable foods and drinking wine to excess.

"'One day Dhanapala kicked Dhrstabuddhi out of the house after he saw him walking along the road arm-in-arm with a prostitute. From then on all Dhrstabuddhi's relatives were highly critical of him and distanced themselves from him. After he had sold his ornaments and become destitute, the prostitutes also abandoned him and insulted him because of his poverty.

"'Dhrstabuddhi was now full of anxiety, and also hungry. He thought, "What should I do? Where should I go? How can I maintain myself?" He then began to steal. The king's constables arrested him, but when they learned that his father was the famous Dhanapala, they released him. He was caught and released many times. But at last the ill-mannered Dhrstabuddhi was apprehended, handcuffed, and then beaten. After whipping him, the king's marshals warned him, "0 evil one! There is no place for you here."

"'However, Dhrstabuddhi was freed from his tribulation by his father and immediately thereafter entered the dense forest. He wandered here and there, hungry and thirsty and suffering greatly. Eventually he began killing lions, deer, boars, and wolves for food. Always ready in his hand was his bow, always on his shoulder his quiver full of sharp arrows. He also killed many birds, such as cakoras, peacocks, kankas, doves, and pigeons. He unhesitatingly slaughtered many species of birds and animals, and thus his sins mounted day by day. On account of his previous sins, he was now immersed in an ocean of great sin.

"'Dhrstabuddhi was always miserable and anxious, but one day, during the month of Vaisakha, by the force of some of his past merit he chanced upon the sacred asrama of Kaundinya Muni. The great sage had just finished bathing in the Ganges River, and water was dripping from him. Dhrstabuddhi had the great good fortune to touch some of those drops falling from the sage's clothes. Instantly Dhrstabuddhi was freed of ignorance, and his sinful reactions were reduced. Offering his humble obeisances to Kaundinya Muni, Dhrstabuddhi prayed to him with joined palms: "0 great brahmana, please describe some kind of atonement I may perform without too much endeavor. I have committed so many sins in my life, and these have now made me very poor."

"'The great risi replied, "0 son, listen with great attention, for by hearing me you will become free of all your remaining sins. In the light fortnight of this month, Vaisakha, there occurs the sacred Mohini Ekadasi, which has the power to nullify sins as vast and weighty as Mount Sumeru. If you follow my advice and faithfully observe a fast on this Ekadasi, which is so dear to Lord Hari, you will be freed from all the sinful reactions of many, many births."

"'Hearing these words with great joy, Dhrstabuddhi promised to observe a fast on Mohini Ekadasi, according to the sage's instructions. 0 best of kings, 0 Rama, by fasting completely on Mohini Ekadasi, the once-sinful Dhrstabuddhi, the prodigal son of the merchant Dhanapala, became sinless. Afterward he achieved a beautiful transcendental form and, free at last of all obstacles, rode upon Garuda, the carrier of Shree Hari, to the Lord's supreme abode.

'0 Rama, the fast day of Mohini Ekadasi removes the darkest illusory attachments to material existence. There is thus no better fast day in all the three worlds."'

Lord Krishna concluded, "And so, 0 Yudhisthira, there is no place of pilgrimage, no sacrifice, and no charity that can bestow merit equal to even one sixteenth of the merit a faithful devotee of Mine obtains by observing Mohini Ekadasi, And He who hears and studies the glories of Mohini Ekadasi achieves the merit of giving away one thousand cows in charity."
