One day while playing with his friends in Gokula, the child Krishna lost the ball in the Yamuna river.
[5] At Tulsi ghat, a large Kadamba tree branch is planted at the edge of the river Ganga.
Propelled by human assistants, the serpent effigy along with the boy Krishna on its head make a circular sweep in the water, parading in front of thousands of spectators, who watch the display from the river bank or from boats floating on the river waters.
