Empyrean
The Empyrean Heaven or Empyrean (Latin: empyreus "in the fire", from ancient Greek: ἔμπυρος émpyros), the Fire Heaven, is, according to ancient and medieval cosmology, the outermost and highest heavenly sphere filled with divine fire and light, still above the Crystal Heaven. It corresponds to the Nirvana of the Eastern tradition or the Ain Soph of the Kabbalists. According to later Christian views, it is the seat of the devine Trinity and the blessed and is also described in this way in Dante's Divine Comedy.
Paul describes in 2 Corinthians how he was caught up into the Third Heaven. The first heaven corresponds to the circle of air, the second to the celestial spheres with the planets and stars, especially the zodiac, and finally the third to the Empyrean.

Though there is nothing to be gained by it, I will go on to visions and revelations of the Lord. 2 I know a man in Christ who fourteen years ago was caught up to the third heaven—whether in the body or out of the body I do not know, God knows. 3 And I know that this man was caught up into paradise—whether in the body or out of the body I do not know, God knows— 4 and he heard things that cannot be told, which man may not utter. 5 On behalf of this man I will boast, but on my own behalf I will not boast, except of my weaknesses -“
