After Beatrice appears, first as a channel emerging from deep within the Chariot, and connecting the Pilgrim to God’s Love and Power (The “Ancient Love”), something extraordinary happens.
Virgil disappears, in large part since a direct connection with God is outside the bounds of Reason’s capacity. But Beatrice’s function also changes, in terms of what she means.
In short; Beatrice is your inner spiritual life, through which you will sense the Divine directly, but it will also be an immature “faculty” at its new “birth” within you. Just as Virgil goes through a series of changes throughout Inferno and Purgatory, Beatrice will also change, and she makes mistakes in the beginning.
Meaning; your inner spiritual life and soul need growth and adjustments. Which we see here in Canto 30; instantly after we had the touch of the “hidden virtue that moved from her”, that made the Pilgrim feel “the great power of the ancient love”, Beatrice falls into a different mode and starts her first speech with the word “Dante,”. And she starts aggressively attacking him for his failures and shortcomings. But this is not the voice of God. This is the voice of Dante himself, his own spiritual life being full of self-resentment and self-accusations. In a way, this is your own inner critic, detached from the true heavenly life and realities. So this is the second time one will “meet oneself” at the biggest thresholds, the first was accepting God’s Love in the Wall of Fire, the second is how your inner spiritual life might start attacking you strongly, for your own faults.
“She” is right in many things she is saying, but she goes about it in a wrong way. Which is why the angels start singing to the Pilgrim, and directly address Beatrice for being too harsh. They represent the true voice of the Heavens, while Beatrice is the newborn, nascent spiritual soul in oneself, veiled, and the beginning a new journey of growth and discovery.
And here comes the much bigger point; what Dante is doing here is setting up a new dynamic for the rest of the Comedy. Rather then reading this is in single-mode, we need to see this through the “dual perception”, of God AND Beatrice. This is the new dynamic. Your soul and God, and the growing spiritual consciousness and wisdom within you, gathered through a constant “churning” and dynamic with the Heavens. As we see shown instantly; Beatrice being too hard, the angels very gently guiding her to a bigger spiritual wisdom.
So in a way, Dante the Writer creates a new “carro” for us; your soul (Beatrice) and God. Which is also why he twice specifies that Beatrice is on the “left side” of the Chariot (la sinistra, and la detta coscia).
Moreover, this sheds a new light on the Garden of Eden. It becomes here the place where you establish a new relationship with God, and a dynamic learning one, through a new carro.
This is the foundation of a new journey, and this is the new carro that will bring us up through the spheres with an increasingly wise and radiant Beatrice, and the one that ultimately will bring us to full communion and union, with the Heavens.
