In plain words
The poet, to the Lord: O you of such nature, who are born in every kind of being, at one with it, and rise ever higher above it! You who lie on the serpent bed in the vast sea of the three waters [of rivers, rain and springs]: for those who stand with hearts filled with devotion to you, and have let go every other attachment, there is joy in every way, here [in this world], there [in the highest heaven], and everywhere [on the way between].
