maya nirupitas tubhyam

tvam abhadram asammatam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The King of the Yavanas replied: After much consideration, I have arrived at a husband for you. Actually, as far as everyone is concerned, you are inauspicious and mischievous. Since no one likes you, how can anyone accept you as his wife?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After much consideration, the King of the Yavanas decided to make the best use of a bad bargain. Kalakanya was a bad bargain, and no one liked her, but everything can be used for the service of the Lord. Thus the King of the Yavanas tried to utilize her for some purpose. The purpose has already been explained — that is, Kalakanya as jara, the invalidity of old age, can be used to arouse a sense of fear in people so that they will prepare for the next life by engaging in Krsna consciousness.
