rsayo manavo deva
kalah sarve harer eva
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
All the rsis, Manus, demigods and descendants of Manu, who are especially powerful, are plenary portions or portions of the plenary portions of the Lord. This also includes the Prajapatis.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Those who are comparatively less powerful are called vibhuti, and those who are comparatively more powerful are called avesa incarnations.
