ekadasyam samayantyam prapunantyam jagattrayam
sthatavyam annamasritya bhavata papa purusa
sansare yani papani tany eva ekadasi dine
annam asritya tisthanti sriman narayana ajnaya
(Padma Purana, Kriya Yogasara 22.46,50)
When Ekadasi arrives, at that time, all of the sins from the three worlds reside in grains in the form of a sinful person.
Whatever sins are available in this world, they all together reside in grains on Ekadasi day by the order of Lord Sri Narayana.
