Katyayani Vrata is observed in Margashirsh month in North
India and is dedicated to Goddess Katyayani form of Goddess Durga. The story of Katyayani Vrata is associated with Sri Krishna playing prank on the Gopis in Braj. Katyayani
Vrat Katha is as follows:
One day the gopis of Braj were observing Katyayani Vrat, as
usual, went to Yamuna River took off their clothes, placed them on the bank and
started having bath. While practicing this austerity they prayed to the Goddess
to make Krishna as their husband.
Lord Krishna was aware of their wishes. The boy Krishna came
there, took away their clothes, and sat on a branch of a Kadamba Tree.
He then called upon the gopis to come out of the water to
collect their clothes one by one.
