Yudhishthira Maharaj said, “Oh Madhusudana, what is the name of the Ekadashi that comes during the light fortnight of the month of Ashvina (September – October)? Please be merciful and disclose this truth to me."
The Supreme Personality of Godhead Sri Krishna replied, "Oh king, please listen carefully as I explain the glories of Pashankusha Ekadashi – which removes all sins. On this day one should worship the Deity of Padmanabha, the lotus naveled Lord Vishnu, according to the rules of archana viddhi (regulations). By so doing, one achieves whatever heavenly pleasures one may want in this world, and at last attains liberation from this world thereafter. Simply by offering one's humble obeisances unto Lord Vishnu, one can achieve the same merit as is gained by performing great penances for a long time restraining and controlling the senses. Although a person might have committed unlimited and abominable sins, he can still escape hellish punishment just by paying his obeisances to Lord Sri Hari, the taker away of all sins."
"The merits gained by going on pilgrimage to the Holy Tirthas of this earthly planet can also be achieved simply by chanting the Holy names of Lord Vishnu. Whosoever chants these sacred names – such as Rama, Vishnu, Janardana or Krishna – especially on Ekadashi never sees Yamaraj, the king of death's punishing abode. Nor does such a devotee who fasts on Pashankusha (Papankusha) Ekadashi, which is very dear to Me, see that hellish place."
"Both the Vaishnava who criticizes Lord Shiva and the Shaivite who criticizes Me certainly go to hell. The merit obtained by performing one hundred horse sacrifices and one hundred Rajasurya sacrifices is not even equal to one sixteenth of the merit a devotee is able to attain by fasting on Ekadashi. There is no higher merit one can achieve than that attained by fasting on Ekadashi. Indeed, nothing in all the three worlds is as pleasing or as able to purify one of accumulated sin as Ekadashi, the day of the lotus-naveled Lord, Padmanabha.”
"O king, until a person observes a fast on the day of Lord Padmanabha named Papankusha Ekadashi, he remains sinful, and the reactions of his past sinful activities never leave him like a chaste wife. There is no merit in all the three worlds that can match the merit that one gains by observing a fast on this Ekadashi. Whosoever observes it faithfully never has to see death personified, Lord Yamaraj. One who desires liberation, elevation to the heavens, good health, wealth, and food grains should simply fast on this Pashankusha Ekadashi. O king, neither the Ganges, Gaya, Kashi, nor Pushkara, nor even the holy site of Kurukshetra, can grant as much auspicious merit as this Papankusha Ekadashi.
O Maharaj Yudhishthira, protector of the earth, after observing Ekadashi during the daytime, the devotee should remain awake through the night, absorbed in hearing, chanting and serving the Lord – for by so doing he easily attains to the Supreme abode of Lord Vishnu. Not only that, but ten generations of ancestors on his mother's side, ten generations on his father's side, and ten generations on his wife's side are all liberated by a single observance of a fast on this Ekadashi. All these ancestors attain their original, four armed transcendental Vaikuntha forms. Wearing yellow garments and beautiful garlands, they ride to the spiritual realm on the back of Garuda, the renowned great enemy of the snakes. This is the benediction My devotee earns simply by observing one Papankusha Ekadashi properly.
"O best of kings, whether one is a child, a youth, or in old age, fasting on Papankusha Ekadashi frees him from all sins and makes him immune to suffering a hellish rebirth. Whosoever observes a fast on the Papankusha Ekadashi becomes free of all his sins and returns to the spiritual abode of Lord Sri Hari. Whosoever donates gold, sesame seeds, fertile land, cows, grain, drinking water, an umbrella, or a pair of shoes on this most auspicious of Holy days will never have to visit the abode of Yamaraj, who always punishes the sinners. But if a resident of earth fails to perform spiritual deeds, especially the observance of a fast on days such as Ekadashi, his breathing is said to be no better, or of as much use as the breathing/puffing of a blacksmith's bellows.
O best of the kings, especially on this Papankusha Ekadashi, even the poor should first bathe and then give some charity according to their means, and perform other auspicious activities in accordance with their ability.
Whosoever performs sacrifices and benefits the people or builds public ponds, resting places, gardens or houses do not suffer the punishments of Yamaraj. Indeed, one should understand that a person must have performed such pious activities as these in the past life if he is long lived, wealthy, of high birth or free from all diseases. But a person who observes Papankusha Ekadashi goes to the abode of the Supreme Personality of Godhead, Vishnu.”
Thus ends the narration of the glories of the Pashankusha Ekadashi or Papankusha Ekadashi, or Ashwina-shukla Ekadashi, from the Brahma-vaivarta Purana.
This year Pashankusha Ekadashi falls on October 20, 2018.
