ITRANS:

Translation:
Thereafter, from the partial representation of Brahmā, the moon-god was born of them; from the partial representation of Viṣṇu, the great mystic Dattātreya was born; and from the partial representation of Śaṅkara [Lord Śiva], Durvāsā was born. Now you may hear from me of the many sons of Aṅgirā.
