In plain words
The poet, of the Lord: If one knows them well by knowledge that is love, and, standing at love's furthest reach, recites the names that tell Nārāyaṇa's own nature and the other names that tell his glory, he will make that one an immortal who adorns heaven [one of his eternal attendants in Paramapadam]. Is that not the very nature of the Lord of the immortals who serve him, our own kin?
