In plain words
The poet, singing Rāma of Kaṇṇapuram to sleep: O child, glory of the line of Kausalyā, whose dark locks are rich with fragrance! O noble son-in-law of Janaka of great and lasting fame! O son of Daśaratha! My dark gem of Kaṇṇapuram, richer in holy waters even than the Gaṅgā! Sweet nectar of our royal clan! Rāghava, tālēlō.
