In plain words
The poet: I have taken up servitude to him and got free of the miseries of birth [the sense of 'I' and 'mine']. I am so filled [with knowledge and devotion] that the gods [Brahmā and the rest] cannot come near me. Letting go of heaven and its like and of this earth, I am filled now with longing to see the supreme and spacious land [Vaikuṇṭha].
