The door-keeper went to look for Raikva, but returned saying, 'I found him not.' Then the king said: 'Alas! where a Brâhmana should be searched for (in the solitude of the forest), there go for him.'

In plain words: The servant went to find Raikva but came back saying he could not find him. The king told him to look in the quiet, lonely places where a holy man would live.
