I really loved Sona's Durga roop and I think it was the best ever .The incidents could have been shown more and in a grand way,like the Rudra avatar. But any way. I found in Wikipedia about this information.
Once after their marriage, Shiv and Parvati goes to Himavan to live. There Shiv gets angry at Parvati for some reason and leaves the palace. In order ro stop him, Parvati takes 10 roops at 10 places of the palace.
Any one knows about this myth? I think we may see this before birth of Karthikeay.
