Parvati's Test

Parvati prays in front of Shivling for Mahadev to come there. She sits there for hours but Mahadev doesn't appear. Kartikeya and Ganesh decide to go to Mahadev and ask him to come themselves. Mahadev tests Parvati by letting go the water of Ganga from his hair to the place Parvati is praying.
