In plain words
The poet, singing Rāma of Kaṇṇapuram to sleep: O you who went to the ancient forest with all your kin following behind! O rare medicine for those who are yours alone! O lord of the city of Ayōdhyā! My dark gem of Kaṇṇapuram, where the learned dwell! O you who obeyed the word of your stepmother [Kaikēyi]! Śrīrāma, tālēlō.
