All the ṛṣis, 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 Prajāpatis.
Those who are comparatively less powerful are called vibhūti, and those who are comparatively more powerful are called āveśa incarnations.
