In each age, the infallible Lord’s appearance in this world among the animals, human beings, sages and devatās is called protection of the universe. By these incarnations he kills the enemies of Vedic culture. Poṣaṇam was defined as mercy of the Lord previously. Now poṣaṇam is called raksā. Rakṣā is explained. The activities of the Lord’s avatāras among animals, humans and devatās, which are the cause of his appearing, are called rakṣā. Why does he appear? The demons are killed by the avatāras. Thus rakṣā means protecting his devotees from the afflictions of the wicked. As well sometimes rakṣā simply means protecting his devotee from great fear (without a demon being involved). Thus the protection of Ajāmila and others in the Sixth Canto is called rakṣā.
