In plain words
The poet, of the Lord: His mother [Kausalyā] followed behind him and begged him to stay, but he would not heed her; the Lady of the beautiful flower [Sītā], her shoulders like great bamboo, herself begged to go before him. For all that the matchless, noble one did then, strong of arm and holding fast to the word [of his father], only his measuring of the wide earth is equal.
