Pragâpati said to them: 'After you have adorned yourselves, have put on your best clothes and cleaned yourselves, look again into the water-pan.' They, after having adorned themselves, having put on their best clothes and cleaned themselves, looked into the water-pan. Pragâpati said: 'What do you see?'

In plain words: Prajapati tells the two students to dress up in their best clothes, clean themselves, and look into the water again. Then he asks them what they see.
