The nature of the universe which stilleth
the centre and moveth all the rest around
hence doth begin as from its starting point
And this heaven hath no other where than the Divine mind.
—Dante Alighieri, Paradiso, Canto xxvii, 106–110
"Thanks to the Holy Spirit, who helps us understand Jesus' words and guides us to the whole truth (cf. Jn 14: 26; 16: 13), believers can experience, so to speak, the intimacy of God himself, discovering that he is not infinite solitude but communion of light and love, life given and received in an eternal dialogue between the Father and the Son in the Holy Spirit - Lover, Loved and Love, to echo St Augustine."
