As the high saints were borne away I heard their holy voices say: “In this pure grove, O devotee, Prince Ráma soon will visit thee. When he and Lakshmaṇ seek this shade, Be to thy guests all honour paid.

In plain words: Shabari says that as her teachers rose to heaven, they told her that Rama and Lakshmana would soon visit her grove. They told her to honor them well as guests.
