muhūrtayāte tasmiṃstu kaṇvo'pyāśramamāgamat |
śakuntalā ca pitaraṃ hriyā nopajagāma tam || 23 ||

"The moment the king had left, Kanwa arrived at his abode. But Sakuntala, from a sense of shame, did not go out to receive her father. That great ascetic, however, possessed of spiritual knowledge, knew all. Indeed beholding everything with his spiritual eye, the illustrious one was pleased, and addressing her, said, 'Amiable one, what hath been done by thee today in secret, without, having waited for me--viz., intercourse with a man--hath not been destructive of thy virtue. Indeed, union according to the Gandharva form, of a wishful woman with a man of sensual desire, without mantras of any kind, it is said, is the best for Kshatriyas. That best of men, Dushmanta, is also high-souled and virtuous. Thou hast, O Sakuntala, accepted him for thy husband. The son that shall be born of thee shall be mighty and illustrious in this world. And he shall have sway over the sea. And the forces of that illustrious king of kings, while he goeth out against his foes shall be irresistible.'
