Why does Lasaraleen think Aravis should marry Ahoshta Tarkaan?

From the text:

When Aravis had finished telling her story, Lasaraleen said, "But darling, why don't you marry Ahoshta Tarkaan? Everyone's crazy about him. My husband says he is beginning to be one of the greatest men in Calormen. He has just been made Grand Vizier now old Axartha has died. Didn't you know?"
"I don't care. I can't stand the sight of him," said Aravis.
"But darling, only think! Three palaces, and one of them that beautiful one down on the lake at Ilkeen. Positively ropes of pearls, I'm told. Baths of asses' milk. And you'd see such a lot of me."
