O moon-faced, come O good-natured

Story Play (Attakkatha): 
As the Pandavas in disguise took up the various jobs handed to them by the King of Virata, Panchali, in the role of a royal chambermaid and taking the name Sairandhri, reached the palace and Queen Sudeshna spoke to her thus.
O moon-faced, come O good-natured,
listen to my words, my girl
You have gait like an elephant, beautiful cheeks
and hair to rival peacock feather
Who are you? You seem to be the epitome of beauty
Seeing your beauty today my heart is brimming with delight
Are you Indira? Are you Rati? Or one of the celestial beauties?
kindly tell me the truth and clear my confusion.
