In plain words
The poet, of the Lord's dwelling: The cowherd [Kṛṣṇa] who broke the kuruntam tree has taken these for his dwellings: the Sea of Milk, Vēṅkaṭam, the serpent [Ananta], cool heaven [Paramapadam], the ocean of scripture, and the minds of those [yogis] whose senses rest fixed upon the lotus of the heart that the subtle scriptures speak of.
