Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sakuntala said: I am the daughter of Visvamitra. My mother, Menaka, left me in the forest. O hero, the most powerful saint Kanva Muni knows all about this. Now let me know, how may I serve you?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sakuntala informed Maharaja Dusmanta that although she never saw or knew her father or mother, Kanva Muni knew everything about her, and she had heard from him that she was the daughter of Visvamitra and that her mother was Menaka, who had left her in the forest.
